Titanium ingot

- Jan 29, 2018-

Titanium is a metal element, gray, atomic number 22, relative atomic mass 47.87. Can be burned in nitrogen, high melting point. According to Huacheng Metal online understanding, blunt titanium and titanium-based alloy is a new type of structural materials, mainly for the aerospace industry and marine industry. [1] 

Titanium density of 4.506-4.516 g / cm (20 ℃), higher than aluminum and lower than iron, copper, nickel. But the strength is located in the metal first, is three times the stainless steel, aluminum alloy is 1.3 times. Melting point 1668 ± 4 ℃, melting latent heat 3.7-5.0 kcal / gram atom, boiling point 3260 ± 20 ℃, latent heat of vaporization 102.5-112.5 kcal / gram atom, critical temperature 4350 ℃, critical pressure 1130 atmospheric pressure. Titanium thermal conductivity and conductivity is poor, similar or slightly lower than the stainless steel, titanium with superconductivity, titanium superconducting critical temperature of 0.38-0.4K. At 25 ° C, the heat capacity of titanium is 0.126cal / gram atom, enthalpy 1149 cards / gram atom, entropy is 7.33 cards / gram atom, metal titanium is paramagnetic material, permeability is 1.00004.

Titanium with plasticity, high purity titanium elongation of up to 50-60%, section shrinkage up to 70-80%, but the strength is low, not suitable for structural materials. Titanium impurities in the existence of its mechanical properties of great impact, especially the gap impurities (oxygen, nitrogen, carbon) can greatly improve the strength of titanium, significantly reduce its plasticity. Titanium as a structural material has good mechanical properties, that is, by strictly controlling the appropriate impurity content and adding alloying elements to achieve.
