Titanium alloy is mainly used to make aircraft engine compressor parts, followed by rockets, missiles and high-speed aircraft structural parts.

The density of titanium alloys is generally at 4.51g/cm, which is only 60% of that of steel.The density of pure titanium is close to the density of ordinary steel.Some high-strength titanium alloys exceed the strength of many alloy structural steels, so the specific strength (strength/density) of titanium alloys is much higher than that of other metal structural materials, which can produce parts with high unit strength, good rigidity and light weight.

The Physical phenomenon of titanium alloy processing. 

Although the cutting force of processing titanium alloy is only slightly higher than that of steel with the same hardness, the physical phenomenon of processing titanium alloy is much more complex than that of steel, which makes the difficulty of titanium alloy processing rise linearly.When processing thin wall or ring or other easily deformed parts,this problem appears to be more serious.It is not easy to process thin - walled parts of titanium alloy to the expected size accuracy,as the material of the part is pushed by the tool, the local deformation of the thin wall has exceeded the elastic range ,so caused plastic deformation,and the material strength and hardness of cutting point will increase obviously.
