Titanium is a new type material, its performance depend on the carbon, nitrogen, hydrogen, oxygen and other impurity content. Impurity content of The most pure iodide titanium less than 0.1%, low strength and high plasticity. The performance of 99.5% pure titanium: density ρ = 4.5g/cm3, melting point is 172 silicon alloy wear-resistant 5 ℃, thermal conductivity λ = 15.24W / (mK), tensile strength σb = 539MPa, elongation δ = 25%, reduction of area ψ = 25%, elastic modulus E = 1.078 × 105MPa, hardness HB195
High strength
The density of titanium is about 4.5g/cm3, as like 60% of steel, titanium's strength was close to the strength of ordinary steel, some alloy titanium's high-strength better than structural steel. That's say, specific strength of titanium alloy (strength / density) is much more larger than other metal structural material, see Table 7-1. It can be made high strength, rigid, lightweight parts and components. It be used in the aircraft engine components, skeleton, skin, fasteners and landing gear.
Good corrosion resistance
In wet air and seawater, the corrosion resistance of Titanium is more better than stainless steel; good resistance of pitting, etching; the same as alkali, chloride, chlorine, organic materials, nitric acid, sulfuric acid. However, poor corrosion resistance for reduction of oxygen and chromium salts medium .
Good performance at low temperature. |
