Properties of titanium
1.Density is small, strength is higher: titanium density is 4.51 g/cm3, it is below aluminum and above the steel, copper, nickel, but its strength is located in the top of the metal.
2.Corrosion resistance: titanium metal is a very lively, the equilibrium potential is very low, the thermodynamic corrosion tend to be large in the medium.But in fact, titanium is stable in many medium, such as titanium in oxidizing, neutral and weak reducing medium is corrosion resistant.
3.Good Heat resistant performance : the new titanium alloy is long-term use at 600 ℃ or higher temperature.
4.Low temperature resistant performance is good: titanium alloy TA7 al (Ti - 5-2.5 Sn), TC4 (Ti 6 al 4 v) and Ti - 2.5 - Zr - 1.5 Mo, such as represented by the low temperature of titanium alloy, its strength increase with the decreasing of temperature, but the plastic changes are much less.In - 196-253 ℃ low temperature keep the good ductility and toughness, avoid cold brittleness, the metal is a cryogenic vessel, tank and other equipment ideal material.
5.Strong damping resistance: titanium by mechanical vibration, electric vibration, compared with steel, copper, its longest vibration attenuation.
6.Nonmagnetic, non-toxic: titanium is nonmagnetic metal, will not be magnetized in large magnetic field, non-toxic and has good intermiscibility with human tissue and blood, so adopted by the medical community.
7.Tensile strength and yield strength approach: the performance of titanium shows its showed high (tensile strength/yield strength), said the titanium material in forming the plastic deformation.Because of titanium yield limit and elastic modulus ratio is large, to make the titanium forming ability to rebound.
8.Low modulus of elasticity: titanium elastic modulus at normal temperature is 106.4 GMPa, 57% of the steel.
9.Suction performance: titanium is a kind of chemical nature very lively, metal at high temperature can react with many elements and compounds.Titanium getter mainly refers to the heat react with carbon, hydrogen, nitrogen, oxygen.
