The hardness of titanium alloy is very low, which is only about 1/4 of the 45 steel, but titanium alloy has good strength, so the elastic modulus is small, low modulus of elasticity is elastic. In addition to the higher hardness of titanium alloy than stainless steel, the finished product in the weight is much lighter than ordinary stainless steel screws. In addition, the titanium alloy screw and nut has hard thread, wear resistance performance may also be higher than the general stainless steel, but not easily slip teeth, material stability of titanium alloy itself is also very high, it also has good oxidation resistance.

Some titanium alloy hardness difference is big, so the titanium alloy screw must use good material, the good titanium alloy just has the same hardness with steel.

In life, there are many places using the titanium alloy screws. However, understanding the titanium alloy screw is the hard truth, or it will have inferior counterproductive to choose the fake products.
