1.High strength titanium Gr.5 alloy

The density of titanium alloy is generally about 4.51g/cubic centimeter, which is only 60% of steel. The strength of pure titanium is close to that of ordinary steel. 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 that of other metal structural materials.

2.High thermal strength of titanium Gr.5 alloy

The service temperature is several hundred degrees higher than that of aluminum alloy, and it can still maintain the required strength at medium temperature, and can work for a long time at the temperature of 450~500°C. Titanium alloy still has high strength in the range of 150°C~500°C.

3.Titanium Gr.5 alloy has good corrosion resistance

Titanium alloy works in humid atmosphere and seawater medium, and its corrosion resistance is far superior to that of stainless steel; it is particularly strong against pitting corrosion, acid corrosion, and stress corrosion; it has excellent corrosion resistance against alkali, acid, etc.

4.Titanium Gr.5 alloy has good low temperature performance

Titanium alloys can still maintain their mechanical properties at low and ultra-low temperatures. Titanium alloys with good low-temperature performance and extremely low interstitial elements, such as TA7, can maintain certain plasticity at -253°C. Therefore, titanium alloy is also an important low-temperature structural material.
