What is the difference between pure titanium screw and titanium alloy screw

Titanium screw, pure titanium is a chemical element, chemical symbol Ti, atomic number 22, the appearance of steel, silver luster, is a transition metal, pure titanium screw strength, low density, high hardness, high melting point, corrosion resistance is strong; Due to its stable chemical properties, good resistance to high temperature and low temperature, strong acid and alkali resistance, as well as high strength, low density, it is called "space metal" high purity titanium screw also has good plasticity.

Titanium alloy screw there is a lot of knowledge, titanium alloy is based on titanium to add other elements of the alloy, titanium alloy and titanium aluminum alloy, titanium copper alloy, titanium manganese alloy and other 70 kinds of metal containing titanium elements. The density of titanium alloys is generally about 4.51g/ cubic centimeter, which is only 60% of that of steel, and some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than other metal structure materials, which can be produced with high unit strength, good rigidity and light weight parts. Aircraft use titanium for engine components, skeleton, skin, fasteners and landing gear.
