Product Application

Tungsten is a refractory metal with the highest melting point and the lowest expansion coefficient, and has high resistance to deformation at high temperatures. It is suitable for use in high-temperature furnace components in environments with extremely high temperature requirements: heat shields, heating elements, supports, etc.




Tungsten has a purity of more than 99.95%, with little pollution. It is widely used in the manufacture of electronics and electric light source industry, for example in parts for ion implantation machines, MOCVD heating elements, sputtering targets, etc.

Tungsten has a high density and can be used as a mechanical counterweight; it exhibits poor penetration, and its alloys are mostly used in medical radiation shielding components.
