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.

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.

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. 

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.

Tungsten contact is used in the switch to connect or disconnect the circuit. Tungsten contact has a wide range of applications, covering all fields, such as industry, agriculture, science, technology and national defense as tungsten has the advantages of smooth surface, high hardness, high abrasion resistance, excellent resistance to arc erosion, strong ability to interrupt current, small thermal expansion coefficient and low vapor pressure.

Tungsten carbide powder producing process includes several major steps, namely ingredients calculation, mixing, carbonizing and milling of materials.

Tungsten copper activated liquid phase sintering can improve the miscibility between tungsten and copper and promote the sintering process by means of adding a small amount of Co, Ni, Fe, Pd and other activated elements.

Tungsten copper mechanical alloying is a kind of sintering method by high-energy ball milling.

Tungsten Powder + Copper Powder → High-energy Ball Milling (100 hours, Ar) → Sieving → Pressing (40% Relative Density, 1000~1300℃, H2, 1 hour) → Sintering.

Nanometer tungsten carbide powder can be used as additive materials for high density alloy and tungsten bar and wire, as the combustible agent of explosive industry.
