1, the density is small, high specific strength, the density of titanium metal is 4.51g/cm³ , higher than aluminum and lower than steel, copper, nickel, but the specific strength is located in the first metal.
2, corrosion resistance, not affected by the atmosphere and seawater. At room temperature, it will not be corroded by hydrochloric acid below 7%, sulfuric acid below 5%, nitric acid, aqua regia or dilute alkali solution.
3, good heat resistance, the new titanium alloy can be used at 600℃ or higher temperature for a long time.
4, Good low temperature resistance, good ductility and toughness at -196-253℃, to avoid cold brittleness of metal.
5, strong damping performance, titanium by mechanical vibration, electrical vibration, compared with steel, copper metal, its own vibration attenuation time is the longest.
6, non-magnetic, non-toxic, titanium is a non-magnetic metal, in a large magnetic field will not be magnetized, and non-toxic.
7, Tensile strength is close to its yield strength. This performance of titanium shows that its strength ratio (tensile strength/yield strength) is high, which indicates the plastic deformation of titanium metal when forming. Because the ratio of yield limit to elastic modulus of titanium is large, the springback ability of titanium forming is large.
8, good heat exchange performance, although the thermal conductivity of titanium metal is lower than carbon steel and copper, but because of the excellent corrosion resistance of titanium, so the wall thickness can be greatly reduced, and the surface and steam heat exchange mode for drip condensation, reduce the heat resistance, There is no scale on the surface of titanium, which can also reduce the thermal resistance, so that the heat exchange performance of titanium significantly improved.
9, The elastic modulus is low. The elastic modulus of titanium is 57% of that of steel at room temperature.
10, Inspiratory performance, titanium is a very active metal with chemical properties, which can react with many elements and compounds at high temperature. Titanium inspiratory mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.
