In metals, tungsten metal has the highest melting point, high temperature strength, creep resistance and thermal conductivity, good electrical conductivity and electron emission properties of Tungsten melting point,heavy, hard and brittle, difficult process, but as long as there is a reasonable process, tungsten can be made by powder metallurgy billet, extrusion, forging, rolling, spinning and drawing, and other processing timber. As the plastic processing tungsten improvement in the level of their organization, tensile strength and ductility - brittle transition temperature is greatly improved.
Tungsten alloy of tungsten-based alloys by adding other elements. In metals, the highest, high temperature strength and creep resistance and thermal conductivity, electrical conductivity and electron emission properties of tungsten melting point are good, than the major, in addition to a large number of alloys used in the manufacture of carbide and as additives, tungsten and its alloys are widely used electronic, electric light industry.
