Performance and purpose of titanium alloys of various materials
Industrial pure titanium TA1, TA2, TA3
Excellent stamping performance. Various forms of welding can be carried out with good welding performance, and the welding joint can reach 90% of the strength of the base metal. Easy to cut with saws and grinding wheels, with good mechanical processing performance. Excellent corrosion resistance
Used for parts below 350 ℃ with low stress and parts stamped into various complex shapes. For example, thermal power plant condenser; Pipeline systems, valves, and pumps corroded by marine seawater; Chemical heat exchangers, pump bodies, distillation towers; Seawater desalination system, platinum plated anode; The skeleton, skin, engine components, crossbeams, etc. of an aircraft.
TA6
It has good welding performance and high creep strength, but the process plasticity is low and can deform under hot conditions. The alloy is not sensitive to cuts when subjected to axial loads, and the cutting performance is still good
Parts and welding parts working below 400 ℃
TA7
Poor stamping performance and good thermoplastic properties. Various forms of welding can be carried out with good performance, and the strength and plasticity of the welded joint 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
Structural components that work for a long time below 500 ℃ can be used for various die forgings
TA8
Good thermoplastic properties. It can be welded in various forms with good weldability. The machinability is the same as that of industrial pure titanium. Good antioxidant properties
Long term working parts below 500 ℃. Capable of manufacturing engine compressor discs and blades
TC1
Good stamping performance. It can be welded in various forms with good weldability. The machinability is the same as that of industrial pure titanium. Good antioxidant properties
Parts for work below 400 ℃. Suitable for various sheet metal, stamping and welding parts
TC2
At 350 ℃, the endurance strength of 100h is more than 400MPa, and hot working has good plasticity. Heated to 350-400 ℃, there is no tendency for embrittlement, so it can be used to weld parts that work at high temperatures
Parts, welding parts, die forgings, and bending parts for work below 500 ℃
TC4
Poor stamping performance and good thermoplastic properties. 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. It is one of the most widely used titanium alloys
Parts for long-term operation below 400 ℃
