Titanium has a low density and high specific strength: the density of titanium is 4.51, which is greater than that of aluminum but lower than that of steel, only 1/2 of that of steel, and the strength of titanium is at the top of the metal.
Titanium has strong corrosion resistance: Titanium is a very active metal, its equilibrium potential is very low, and the thermodynamic corrosion tendency in the medium is large. But in fact, titanium is very stable in many media. For example, titanium is corrosion-resistant in oxidizing, neutral and weakly reducing media.
Titanium has good heat resistance: Titanium alloy can be used for a long time at 600℃ or higher.
Titanium has good low-temperature resistance: low-temperature titanium alloys represented by titanium alloy TA7, TC4, etc., whose strength increases with the decrease of temperature, but the plasticity changes little. It maintains good ductility and toughness at low temperatures of -196-253℃, avoids cold brittleness of metals, and is an ideal material for cryogenic containers, storage tanks and other equipment.
Titanium has strong damping resistance: After metal titanium is subjected to mechanical and electrical vibrations, it has the longest vibration decay time compared with steel and copper metals.
Titanium has the characteristics of non-magnetic and non-toxic: Titanium is a non-magnetic metal, and it 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 adopted by the medical industry.
The tensile strength of titanium is close to its yield strength: this property of titanium shows that its yield strength ratio (tensile strength/yield strength) is high, which means that the metal titanium material is poor in plastic deformation during forming. Due to the large ratio of the yield limit of titanium to the modulus of elasticity, the resilience of titanium during molding is large.
Titanium has good heat transfer performance: Although the thermal conductivity of metallic titanium is lower than that of carbon steel and copper, due to the excellent corrosion resistance of titanium, the wall thickness can be greatly reduced, and the heat transfer between the surface and steam is dropwise condensation , Reduce the heat group, the surface can also reduce the thermal resistance without fouling, so that the heat transfer performance of titanium is significantly improved.
The elastic modulus of titanium is low: the elastic modulus of titanium at room temperature is 106.4GMPa, which is 57% of steel.
Titanium has gettering properties: Titanium is a chemically very active metal that can react with many elements and compounds at high temperatures. Titanium getter mainly refers to the reaction with carbon, hydrogen, nitrogen, and oxygen at high temperatures.
