Tungsten carbide button is an extremely hard alloy made from tungsten carbide and binders that offers high wear resistance as well as good corrosion resistance.

In accordance with different manufacturing processes, tungsten crucible are mainly pided into forging tungsten crucible, sintering tungsten crucible, spinning tungsten crucible and stamping tungsten crucible. This is attributed to many of advantages of tungsten, such as high melting point, high boiling point, small coefficient of thermal expansion, and so on. 

About 4-5% of annual worldwide tungsten production is consumed by the lighting industry. The largest market is still for incandescent lamps. However, more than 70% of artificial lighting is today generated by fluorescent lamps and this portion is steadily increasing. Modern production units can produce more than 6000 lamps per hour. Tungsten is used in the forms of wires, coils, and coiled coils in incandescent lamps, and as electrode in low-and high-pressure discharge lamps.

Native tungsten carbide powder refers to WC prepared from native tungsten powder and carbon, black hexagonal crystals with metallic luster, is main raw material for producing hard alloy.
