Metallic properties of titanium ingots

The density of titanium is 4.506-4.516 grams per cubic centimeter (20 ℃), higher than aluminum and lower than iron, copper, and nickel. But its specific strength ranks first among metals, three times that of stainless steel and 1.3 times that of aluminum alloy. Melting point 1668 ± 4 ℃, latent heat of melting 3.7-5.0 kcal/g atom, boiling point 3260 ± 20 ℃, latent heat of vaporization 102.5-112.5 kcal/g atom, critical temperature 4350 ℃, critical pressure 1130 atmospheres. The thermal and electrical conductivity of titanium is poor, approximately or slightly lower than that of stainless steel. Titanium has superconductivity, and the superconducting critical temperature of pure titanium is 0.38-0.4K. At 25 ℃, the specific heat capacity of titanium is 0.126 kcal/g atom · degree, the enthalpy is 1149 kcal/g atom, and the entropy is 7.33 kcal/g atom · degree. Titanium metal is a paramagnetic substance with a magnetic permeability of 1.00004.
