Product Description
Pure titanium is a silver-white metal with many excellent properties. The density of titanium is 4.54g/cm3, which is 43% lighter than steel and slightly heavier than the prestigious light metal magnesium. The mechanical strength is about the same as that of steel, twice that of aluminum and five times that of magnesium. Titanium is resistant to high temperatures, with a melting point of 1942K, which is nearly 1000K higher than gold and nearly 500K higher than steel.
Detailed Photos
High strength: The density of titanium alloy is generally about 4.51g/cubic centimeter, which is only 60% of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels.
High chemical activity: Titanium has high chemical activity, and has strong chemical reactions with O, N, H, CO, CO2, water vapor, ammonia, etc. in the atmosphere.
Good corrosion resistance: Titanium alloy works in humid atmosphere and seawater medium, and its corrosion resistance is better than stainless steel; it is particularly resistant to pitting corrosion, acid corrosion, and stress corrosion; it is resistant to alkali, chloride, gas, etc. Organic substances, sulfuric acid, etc. have excellent corrosion resistance.
Low temperature resistance: 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.
High thermal strength: the use temperature of titanium 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 a temperature of 450~500°C. There is still a high specific strength in the high range, but the specific strength of aluminum alloy decreases obviously at 150C. The working temperature of titanium alloy can reach 500°C, while that of aluminum alloy is below 200°C.
Small thermal conductivity: the thermal conductivity of titanium = 15.24W/ (m.K) is about 1/4 of brocade, 1/5 of iron, and 1/14 of aluminum, and the thermal conductivity of various titanium alloys is about 1/4 that of titanium. 50% drop.
