Pure titanium screw, pure titanium is a chemical element, chemical symbol Ti, atomic number 22, looks like steel, with silvery white luster, is a transition metal, pure titanium screw has high strength, low density, high hardness, high melting point, corrosion resistance Strong resistance; due to its stable chemical quality, excellent high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance and high strength, low density, widely known as "space metal", high-purity titanium screws also have excellent plasticity

High Tensile Titanium small size micro screw for watch glass, titanium alloys are alloys based on titanium with other elements involved, including titanium aluminum alloys, titanium copper alloys, titanium manganese alloys and other 70 kinds of titanium-containing metals. The density of titanium alloy is about 4.51g/cm3, which is only 60% of steel. Some high-strength titanium alloys exceed the strength of many structural steel alloys.

​​

Therefore, 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 stiffness and light weight. Titanium alloys are used in aircraft engine components, frames, skins, fasteners and landing gear.
