Titanium alloy bolts have the characteristics of low density and high strength, and are generally applied in places where light weight and strength are both required, but titanium alloy screws do not belong to high-strength materials.

The high strength of titanium alloy bolts is relative to steel screws, and the density of titanium alloy is between 50 and 60 percent of steel, but the strength and steel are comparable.

The hardness of titanium alloy itself is very low, but the strength of titanium alloy is very good, so the elastic modulus of the whole material is very small. Titanium alloy bolts is much lighter than ordinary stainless steel screws, titanium alloy screws and nuts thread wear resistance is higher than ordinary stainless steel, in addition to it is not easy to slip teeth, titanium alloy itself is also very high material stability, with good oxidation resistance.
