Tungsten alloys are alloys of other elements added on the basis of tungsten. Among metals, tungsten has the highest melting point, high temperature strength and creep resistance, and good thermal conductivity, electrical conductivity and electron emission performance. It is widely used in addition to tungsten carbide and its alloys. In the electronics and electric light source industries, it is also used in aerospace, casting, weapons and other sectors for the production of rocket nozzles, die-casting molds, armor-piercing cores, contacts, heating elements and heat shields.

Cemented carbide is the most common and dominant form of tungsten alloy. Unlike the previous tungsten alloys, which are tungsten and carbon, cobalt, it is also often referred to as tungsten-cobalt alloy. At present, the most widely used tools in the industrial field are basically cemented carbide tools, so the tungsten alloy such as cemented carbide is also called "industrial teeth."
