The density of titanium alloy is generally about 4.51g / cubic centimeters, only 60% of the steel, the strength of pure titanium is close to the strength of ordinary steel, some high-strength titanium alloy over the strength of many structural steel. Therefore, the specific strength of titanium (strength / density) is much larger than other metal structure materials.
2.>Good corrosion resistance
Titanium alloys work well in damp atmospheres and seawater media, and their corrosion resistance is much better than that of stainless steel. Titanium alloys are particularly resistant to pitting, acid etching and stress corrosion. Organic materials such as alkali, chloride and chlorine, nitric acid, sulfuric acid Etc. have excellent corrosion resistance
