Physical properties of titanium

Physical properties of titanium

① Density

The density of  titanium  is 4.51g/cm3.

② melting point

The melting point of titanium is (1668±5)℃. 

③ boiling point

The boiling point of titanium is (3260±20) ℃.

④ Specific heat capacity

The specific heat capacity of titanium at 20℃ is 500J/(kg·K), and with the increase of temperature, the specific heat capacity of titanium increases. At 882℃, the specific heat capacity changes suddenly due to the a/β transition.

⑤ Thermal expansion coefficient

The coefficient of thermal expansion of titanium is significantly lower than that of aluminum and steel, which is 7.6×10-6 1/K.

⑥ Thermal conductivity

Titanium has a very low thermal conductivity of 17W/(m·K), similar to 18-8 stainless steel, which causes a large temperature difference along the section when titanium is heated in the ingot and billet, and when the titanium structure is welded, resulting in a large local stress.

⑦ Resistivity

The resistivity of titanium is 0.48μQ·m, and the resistance of titanium is quite high.

⑧ Magnetic susceptibility

The magnetic susceptibility of titanium is 3.4×10-6, and titanium is non-magnetic.

⑨ Elastic modulus

The elastic modulus of titanium is generally 103 ~ 110GPa, which is half of the steel material and easy to bend.
