Fifth, the performance of titanium
1. High strength
The density of titanium alloy is generally about 4.5g/cm3, 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, and parts and components with high unit strength, good rigidity and light weight can be produced. At present, titanium alloys are used for aircraft engine components, skeletons, skins, fasteners and landing gear.
2. High thermal strength
The use temperature is several hundred degrees higher than that of aluminum alloy. It can still maintain the required strength at medium temperature. It can work for a long time at a temperature of 450 to 500 ℃. These two types of titanium alloys are still very high in the range of 150 ℃ to 500 ℃. Specific strength, while the specific strength of aluminum alloy at 150 ℃ significantly decreased. The working temperature of titanium alloy can reach 500 ℃, aluminum alloy is below 200 ℃.
3. Good corrosion resistance
Titanium alloys work in humid atmosphere and seawater media, and their corrosion resistance is far superior to stainless steel; they are particularly resistant to pitting, acid corrosion, and stress corrosion; they are resistant to organic items such as alkali, chloride, chlorine, and nitric acid. Excellent corrosion resistance. But titanium has poor corrosion resistance to media with reducing oxygen and chromium salts.
