1 Titanium has a low density and high specific strength: the density of titanium is 4.51, which is greater than aluminum and lower than steel, only 1/2 of steel, and the strength of titanium is the first in metal.
2 Titanium has strong corrosion resistance: Titanium is a very active metal, its equilibrium potential is very low, and its thermodynamic corrosion tendency in the medium is large. But in fact, titanium is very stable in many media, such as titanium is resistant to corrosion in oxidizing, neutral and weakly reducing media.
3 Titanium has good heat resistance: titanium alloy can be used for a long time at 600 ℃ or higher.
4 Titanium has good low-temperature resistance: Low-temperature titanium alloys represented by titanium alloys TA7, TC4, etc., whose strength increases with decreasing temperature, but the plasticity change is not large. It maintains good ductility and toughness at a low temperature of -196-253 ℃, avoids the cold brittleness of metals, and is an ideal material for low temperature containers, storage tanks and other equipment.
5 Titanium has strong anti-damping performance: After titanium metal is subjected to mechanical vibration and electrical vibration, its own vibration decay time is the longest compared with steel and copper metal.
6 Titanium has non-magnetic and non-toxic properties: Titanium is a non-magnetic metal and will not be magnetized in a large magnetic field. It is non-toxic and has good compatibility with human tissues and blood, so it is used by the medical community.
7 The tensile strength of titanium is close to its yield strength: this property of titanium shows that its yield ratio (tensile strength / yield strength) is high, indicating that the plastic deformation of titanium metal materials is poor during forming. Because the ratio of the yield limit of titanium to the elastic modulus is large, the resilience of titanium during forming is large.
8 Titanium has good heat transfer performance: although the thermal conductivity of titanium is lower than that of carbon steel and copper, the thickness of the wall can be greatly reduced due to the excellent corrosion resistance of titanium, and the heat exchange method between the surface and steam is drop condensation , Reduce the heat group, too small surface without scaling can also reduce the thermal resistance, so that the heat transfer performance of titanium is significantly improved.
9 Titanium has a low modulus of elasticity: Titanium has an elastic modulus of 106.4 GMPa at room temperature, which is 57% of steel.
10 Titanium has gettering properties: Titanium is a very chemically active metal that can react with many elements and compounds at high temperatures. Titanium gettering mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.
