Common grades and applications of titanium alloys
Titanium alloy TA6:
It has good welding performance and high creep strength, but low process plasticity and can deform under hot conditions. Dongri alloy is not sensitive to cutting when subjected to axial loads, and its cutting performance is still good for parts and welded parts working below 400 ℃.
Titanium alloy TA7:
Poor stamping performance, good thermoplasticity. Dongri can perform various forms of welding with good performance, and the strength and plasticity of the welded joints can be equal to the base metal. The mechanical processing performance is the same as that of industrial pure titanium. Good corrosion resistance and high temperature thermal stability. It can be used as a structural component for long-term operation below 500 ℃ and various forging parts.
Titanium alloy TA8:
Good thermoplasticity. Dongri can perform various forms of welding with good weldability. The machinability is the same as that of industrial pure titanium. Long term working parts with good antioxidant properties below 500 ℃. Dongri can manufacture engine compressor discs and blades.
Titanium alloy TC1:
Good stamping performance. Dongri can perform various forms of welding with good weldability. The machinability is the same as that of industrial pure titanium. Parts with good antioxidant properties for working below 400 ℃. Suitable for various sheet metal, stamping, and welding parts.
Titanium alloy TC2:
At 350 ℃, the endurance strength after 100 hours is above 400MPa, and there is good plasticity during hot processing. Heating to 350-400 ℃, there is no tendency for brittleness. Therefore, it can be used to weld parts that work at high temperatures to parts that work below 500 ℃, welded parts, forged parts, and bent parts.
Titanium alloy TC3:
Poor stamping performance, good thermoplasticity. Various forms of welding can be carried out, and the strength of the welded joint can reach 90% of the strength of the base metal. The mechanical processing performance is still good, requiring the use of hard alloy, large cutting volume, slow speed, and sufficient cooling. Good corrosion resistance and thermal stability. Dongri Metal is one of the most widely used titanium alloys for long-term working parts below 400 ℃.

Titanium alloy TC4:
The composition of the material is Ti-6Al-4V, which belongs to the (a+b) type titanium alloy and has good comprehensive mechanical properties. Greater than intensity. The strength of TC4 is sb=1.012MPa, the density is g=4.4 * 103, and the specific strength is sb/g=23.5, while the specific strength of alloy steel is sb/g less than 18. Titanium alloy has low thermal conductivity. The thermal conductivity of titanium alloy is 1/5 of iron and 1/10 of aluminum, and the thermal conductivity of TC4 is l=7.955W/m · K. The coefficient of linear expansion is 7.89 * 10-6 ℃, and the specific heat is 0.612 cal/g ·℃. The elastic modulus of titanium alloy is relatively low. The elastic modulus of TC4 is E=110GPa, which is about half of that of steel, so titanium alloy is prone to deformation during processing. TC4 (Ti-6Al-4V) and TA7 (Ti-5Al-2.5Sn) titanium alloys were surface modified using two implantation schemes. Experiments showed that after ion implantation, the microhardness of the titanium alloy was improved, the sliding friction coefficient was significantly reduced, and the wear resistance was effectively improved To investigate its modification mechanism, X-ray photoelectron spectroscopy (XPS) analysis was performed on injected and non injected samples, and satisfactory results were obtained TC4 titanium alloy has a series of advantages such as excellent corrosion resistance, low density, high specific strength, good toughness and weldability, and has been successfully applied in aerospace, petrochemical, shipbuilding, automotive, mold, pharmaceutical and other sectors.
Titanium alloy TC5:

Titanium alloy TC9:
The thermoplasticity is still good. The machinability is the same as that of T alloy. High corrosion resistance. Parts with good thermal stability and long-term operation below 400 ℃. Can manufacture compressor discs and blades.
Titanium alloy TC10:
