Pure titanium is a non-magnetic metallic element, silver-gray in color, with a high melting point (1668 degrees Celsius) and a relatively low density (4.506-4.516g/cubic centimeter, 20 degrees Celsius). Its thermal conductivity at 25 degrees Celsius is 14.99W/(m·℃), which is only 1/6 of iron and 1/16 of aluminum, which will have an adverse effect on cutting processing and welding.

In addition, its expansion coefficient at 25 degrees Celsius is 8.36×10^-6℃^-1, which is smaller than iron and nickel, which helps to compensate for the thermal stress caused by low thermal conductivity, so it is beneficial in material processing and heat treatment. Its molar heat capacity is 250.344kJ/(mol·℃), linear elastic modulus is 115GPa, shear elastic modulus is 44GPa, and Poisson's ratio is 0.33.In addition, the resistivity of high-purity titanium is 540×10^-9Ω·m, while the resistivity of industrial pure titanium is 650×10^-9Ω·m, and its thermal conductivity is relatively low.

These properties make titanium widely used in aerospace, medical and chemical industries.
