1. High strength: The strength/density ratio of
titanium is superior to other metals, and titanium can be used to make components with high strength, good rigidity and light weight. Titanium is used in aircraft engines, frames, skins, fasteners and landing gear.
2. Anti-corrosion: Compared with stainless steel, titanium alloys have better corrosion effects in humid air and seawater. Titanium has great resistance to pitting corrosion, acid corrosion and stress corrosion. Titanium is resistant to alkalis, chlorides, chlorinated organics, sulfuric acid, and nitric acid.
3. High temperature resistance: The application temperature of titanium is higher than that of aluminum alloy. Titanium can work for a long time at 450-500°C. Titanium alloy stil has high strength at the working temperature of 150-500°C. The working temperature of titanium can reach 500°C.
4. Low temperature resistance: Titanium alloys still have their mechanical properties when working at low or ultra-low temperatures. Titanium alloys with low-temperature resistance and extremely low gaps still have good ductility, so titanium alloys are good low-temperature structural materials.
5. Environmentally friendly metal: The thermal conductivity of titanium is lower than that of carbon steel or copper, but titanium has very good corrosion resistance, so the thickness of titanium can be greatly reduced, and the heat exchange mode is drop-by-drop condensation between titanium and steam . This mode reduces the heat transfer resistance, and there is no scaling on the titanium surface, so that the thermal conductivity of titanium is better.
6. Good thermal conductivity: Titanium is a non-magnetic metal that cannot be magnetized in a large magnetic field, and titanium is non-toxic and compatible with blood, so titanium has been applied in the medical field.
