Due to its excellent properties, this material is also very suitable to be machined into parts.
Advantages of Titanium Parts
High Specific Strength
The density of titanium is 4.51g/cm³, which is higher than aluminum but lower than steel, copper, and nickel, but its strength is much higher than other metals. parts made of titanium are light and strong.
Good Corrosion Resistance
Titanium and titanium alloys are stable in many media, and titanium parts can be used in various corrosive environments.
Good Heat Resistance and Low-Temperature Resistance
Titanium parts can work normally at a high temperature of 600°C and a low temperature of minus 250°C and can maintain their shape without changing.
Non-Magnetic and Non-Toxic
Titanium is a non-magnetic metal and will not be magnetized in a strong magnetic field. Titanium is not only non-toxic but also compatible with the human body.
Strong Resistance to Damping
Compared with steel and copper, titanium has the longest damping time when subjected to mechanical and electrical vibration. It can be used as a tuning fork, vibration element of a medical ultrasonic pulverizer, and vibration film of an advanced audio loudspeaker.
Aerospace Industry
One industry that has been relying heavily on titanium parts is the aerospace industry. This is because titanium parts are not only lightweight but also have high strength and resistance to corrosion. These bolts are essential to ensure that the components of an aircraft are held together securely. The lightweight nature of the titanium parts also helps reduce the aircraft's weight, making it more fuel-efficient.
Medical Technology Industry
The medical technology industry also benefits from using titanium parts. This is because titanium is biocompatible, which is non-toxic to living tissues. Therefore, it is ideal for medical implants, such as artificial joints, that need to be attached to bones. titanium parts in medical implants can also help reduce the risk of rejection by the patient's immune system.
Automotive Industry
Titanium parts are also used in the automotive industry, mainly in high-performance cars. As with aircraft, reducing the car's weight helps improve its performance, and using titanium parts can help with this. The strength and corrosion resistance of the bolts also ensures that they can withstand the high demands of high-performance driving.
Marine Industry
The marine industry also benefits from using titanium parts. This is because boats and ships are constantly exposed to saltwater, which can cause corrosion in most metals. On the other hand, titanium parts are resistant to corrosion and can withstand the harsh marine environment. They are also lightweight, which can help reduce the ship's weight and improve fuel efficiency.
Defense Industry
The defense industry relies on titanium parts due to their strength and resistance to corrosion. These bolts are used in tanks, missiles, and other military equipment. They are also used in body armor to protect troops. The lightweight nature of the bolts helps reduce the equipment's weight, making it easier to transport.
Properties of Titanium Parts
High tensile strength
Titanium parts have higher tensile strength than a lot of other metallic alloys. So much so, that a few titanium alloys have tensile strength equal to that of low-grade stainless steel. This makes titanium and its alloys a great choice for application in areas where higher tensile strength metal is required.
Higher-strength-to-density ratio
One of the greatest properties of titanium is that it has a very high strength-to-weight ratio. This means that titanium parts can provide you the same strength at a much lower weight. As a result, titanium is a very popular material when it comes to saving weight like in Aircraft.
Low thermal conductivity
Since titanium parts have lower thermal conductivity it is safe to use these parts in areas of heat generation. This includes exhaust areas of cars where the temperature is elevated.
Resistant against shearing
Unlike a lot of other metals, titanium requires a very sharp cutting tool to be shaped. This means that it is resistant to normal wear and tear that parts experience. This property of titanium makes it a first choice for a lot of application areas.
Higher modulus of elasticity
Due to the higher modulus of elasticity, titanium is an efficient material for use in the construction of springs. This means that titanium-made products reach the same level of elasticity much earlier than other available options in the industry.
Corrosion-resistant
Corrosion is one of the major issues that you have to consider while selecting a part. However, titanium has a quick oxidation process which forms a protective layer on the titanium material. Subsequently, the material is protected against corrosion.
What Grades of Titanium Are Used for Titanium Parts?
Grade 5 is the most common titanium alloy due to its high strength. It is a commonly welding alloy that can function in structural and pressure-containing components. It has high corrosion resistance in both oxidizing and reducing environments.
Grade 6 is a commonly welded titanium alloy containing aluminum and tin often used for components exposed to elevated temperatures. In addition to its high-strength properties, the alloy has excellent stability, making it a good choice for airframes and jet engines.
Grade 7 titanium alloy is especially useful for low temperatures and pH applications. This is a result of its extreme corrosion resistance.
Grade 11 is a titanium alloy with good high-temperature strength and high corrosion resistance. The alloy is a raw material for components operating in high temperatures, such as chemical and petroleum processing equipment and manufacturing aircraft engines and airframes. Grade 11 is also used to manufacture turbines, liquid hydrogen storage tanks, and other critical equipment. The alloy is easily fabricated by machining, forging, rolling, and extruding.
It applies to manufacturing aircraft components, such as engine parts, airframes, landing gear, fuel systems, and other critical equipment. The alloy is also used to manufacture cryogenic vessels, heat exchangers, distillation columns, and other equipment operating at high temperatures.
Grade 23 is a titanium alloy with good ductility and fracture toughness. It functions mostly in the manufacture of medical implants.
Processes of machining titanium alloys involve conventional machining operations (turning, face milling, high-speed cutting (HSC), milling, drilling), forming operations (cold and hot forming; hydroforming, forging), and alternative machining operations (laser cutting, water-jet cutting, direct metal laser sintering). Machining operations of titanium alloys are considered to be difficult due to their relatively high tensile strength, low ductile yield, 50% lower modulus of elasticity (104 GPa), and approximately 80% lower thermal conductivity than that of steel. The lower modulus of elasticity may cause a greater 'spring back' and deflection effect of the workpiece. Therefore, more rigid set-ups and greater clearances for tools are required.
Titanium Parts Vs Stainless Steel Parts
Stainless Screws are most popular core range of engineering components, with the vast majority of our flagship products being made from this alloy.
As a multi-purpose metal, it is highly versatile and its shiny appearance is as a result of the same element which gives this material its 'rust-free' quality; chromium.
Stainless Steel parts are increasingly popular in the marine and food industries, owing to their improved resistance to corrosion, chemicals and liquids, along with good machinability.
The most obvious advantage of using Grade 5 Titanium Screws over Stainless Steel Screws is the fact that this material offers a higher standard tensile strength, whilst also affording comparable corrosion resistance to 316 grade Marine Stainless Steel, also known A4.
However, similar to the issue of cost vs performance when choosing between Titanium bolts and Steel bolts, opting for Titanium over Stainless Steel will generally result in a higher unit cost, making it a more premium option.
Tips on How to Machine Titanium Parts Effectively
Use the Right Tools and Equipment
First and foremost, you must ensure that you are using the right tools and equipment for the job. This might sound pretty obvious, but it's a crucial step in any machining process. titanium parts are more difficult to machine due to their increased hardness. Always use high-speed steel tools and carbide-tipped bits when cutting titanium. Steel tools will dull quickly when used on this material, while carbide tips cut cleanly and last longer.
Transmit the Generated Heat into the Chip
One important aspect of efficiently machining titanium is transmitting the generated heat into the chip. This helps to keep the workpiece, the tool, and the coolant fluid at a relatively consistent temperature. The most effective way to do this is to use a horizontal spindle machine for titanium machining. Another thing you can do to transmit the generated heat into the chip is to increase the feed rate for the part. A higher feed rate can help to keep the temperature consistent during the machining process. This can be especially helpful when machining parts with large feature sizes.
Increase Coolant Concentration and Pressure
As mentioned, titanium parts have a higher heat conductivity than other metals. Therefore, you should increase the coolant concentration and pressure when machining these materials. Increasing the coolant concentration can help reduce the heat that builds up in the machine. It can also help to keep the workpiece and tool at a relatively consistent temperature, allowing you to increase feed rates for the part. If you are using a water-based coolant, you can increase the concentration of this fluid by adding an antifoaming agent. A good option for an antifoaming agent is sodium salts, which help increase water's boiling point and viscosity.
Avoid Galling
Titanium parts typically have a lower lubricity than other metals. This means that they are more likely to gall during machining. Galling is a phenomenon that occurs when two opposing pieces of metal come into contact, and one piece becomes trapped between the two. Galling can cause the machining process to become much more difficult and significantly reduce tool life. You can help to avoid galling when machining titanium parts by using a smaller feed rate and a lower spindle speed. In addition, if you are already experiencing galling, you can often fix the problem by increasing the coolant concentration. This can help break the existing gall and allow you to continue the machining process.
Caring for Titanium Parts
Basic Cleaning and Maintenance
Regular Cleaning: To keep titanium parts in top condition, regular cleaning is essential. Use a soft cloth and mild soap solution to gently wipe the surface. Avoid using abrasive materials or harsh chemicals that can scratch or etch the surface. For automotive parts, ensure that any residues from road salts or environmental contaminants are promptly removed to prevent surface pitting.
Rinsing: After washing with soap, thoroughly rinse titanium parts with clean water to remove any soap residue. This is particularly important in environments where the water may contain minerals that could deposit on the surface.
Drying: Always dry titanium components immediately after washing to prevent water spots. A clean, soft towel is ideal for this purpose.
Preventative Measures
Protective Coatings: Applying a protective coating can enhance the corrosion resistance of titanium parts. These coatings can also add a layer of defense against minor scratches and environmental elements.
Storage Conditions: Store titanium parts in a cool, dry place. Excessive humidity or contact with other metals can sometimes cause galvanic corrosion, even in titanium. Ensure that storage conditions are stable and that titanium is not stored in direct contact with materials like carbon fiber or metals that could catalyze corrosion.
Dealing with Exposure to Harsh Environments
Immediate Cleaning: If titanium parts are exposed to harsh conditions, such as saltwater or industrial chemicals, immediate cleaning is crucial. Prolonged exposure can lead to surface degradation, even with titanium's robust properties.
Post-Cleaning Inspection: After cleaning, inspect the parts for any signs of damage, such as corrosion or wear. This is especially important for components used in critical applications, such as racing or aerospace.
Advanced Care Techniques
Polishing: For aesthetic purposes, polishing titanium can restore its original luster. Use a non-abrasive polish and a microfiber cloth to gently polish the surface. Avoid over-polishing, as this can thin the metal and alter its properties.
Ultrasonic Cleaning: For deeply ingrained dirt or grime, ultrasonic cleaning can be an effective solution. This should be done by professionals who understand the nuances of handling titanium to avoid any micro-abrasions.
Handling Repairs and Alterations
Professional Handling: Any repairs or modifications to titanium parts should be handled by professionals who are experienced with titanium. Improper handling during welding or repairing can compromise the structural integrity of the part.
Heat Treatments: Post-repair heat treatments might be necessary to restore the mechanical properties of titanium, especially if the repairs involve significant heat or stress to the metal.
How to Polish Titanium Parts: A Step-by-Step Guide
Step 1: Clean the Parts
Any dirt, debris, or oils present on the surface can interfere with the polishing process and result in an uneven finish. Before beginning the polishing process, it is important to thoroughly clean the titanium parts to remove any dirt, debris, or oils that may be present on the surface. Using a mild soap and water solution is a good way to remove any surface contaminants. After cleaning, be sure to rinse the parts thoroughly with water to remove any residual soap or debris.
Step 2: Select the Right Media
When polishing titanium parts, it's important to use a non-abrasive media to avoid scratching or damaging the surface of the titanium. Plastic media or porcelain media are good choices for this purpose. Plastic media is a relatively soft media that is effective at removing burrs and other surface imperfections from titanium parts. It is available in a range of shapes and sizes, including cones, cylinders, and stars, making it suitable for a variety of part shapes and sizes.
Step 3: Add the Media and Lubricant
Adding the appropriate amount of lubricant, such as water or oil, is an important step when polishing titanium parts using a disc finishing machine. The lubricant helps to reduce friction and heat during the polishing process, which can help to prevent damage to the surface of the titanium. The amount of lubricant that is added will depend on the specific polishing application and the type of media that is being used. In general, a good rule of thumb is to add enough lubricant to fully cover the media and the parts being polished.
Step 4: Start the Machine
Turn on the centrifugal disc finisher and let it run for a few minutes to ensure that the media and lubricant are evenly distributed throughout the machine.
Step 5: Add the Titanium Parts
Once the machine is running smoothly, add the titanium parts to the machine. Be sure to keep an eye on the parts during the polishing process to ensure that they are not being damaged. You may want to periodically check the parts themselves to see if any damage or scratches are appearing on the surface. If you notice any issues, you can adjust the parameters of the polishing process, such as reducing the intensity of the vibration or adding more lubricant.
Step 6: Set the Centrifugal Disc Polishing Machine
Adjust the speed: The speed of the machine affects the polishing time and the level of finish achieved. Adjust the speed based on the size of the titanium parts, the type of media used, and the desired finish. Higher speeds will result in faster polishing times, but lower speeds may be necessary for delicate or intricate parts.
Adjust the timer: Set the timer to the appropriate time based on the type of media, the speed of the machine, and the desired level of finish. Start with a shorter time and check the progress periodically to avoid over-polishing or damaging the parts.
Step 7: Monitor the Polishing Process
It's important to monitor the titanium parts during the polishing process to make sure that they are not being damaged. Some factors that you may want to consider monitoring include the duration of the polishing process, the intensity of the rotation, the amount of lubricant being used, and the condition of the media.
Step 8: Remove the Parts and Clean The centrifugal Disc Finishing Machine
Fter achieving the desired finish, turn off the centrifugal disc finishing machine and remove the titanium parts. Thoroughly rinse the parts with water to remove any residual media or lubricant, and then dry them with a clean, soft cloth. To clean the machine, first, remove any remaining media and lubricant from the bowl. Then, wipe the bowl and all other parts of the machine with a clean, damp cloth to remove any remaining residue. If necessary, use a mild soap and water solution to clean the machine, being careful not to damage any components.
Step 9: Optional Final Polishing
To repeat the process for achieving a higher level of polish on titanium parts, you can start by removing the plastic media and cleaning the centrifugal disc finishing machine as described earlier. Then, add the porcelain media to the machine and add a water-based lubricant. Turn on the machine and let it run for a few minutes to ensure the even distribution of the media and lubricant. Add the titanium parts to the machine and run it for the desired amount of time to achieve the desired finish.
Step 10: Drying the Parts
After rinsing the parts with water, it's important to dry them thoroughly before storing or using them. A hot air centrifugal drying machine is an effective way to dry the parts quickly and efficiently. Place the titanium parts in the machine and turn it on, making sure that the parts are evenly spaced and not touching each other. Leave the parts in the drying machine until they are completely dry.
