Tungsten carbide plate

Tungsten Carbide plate

Performance features

Excellent red hardness, high hardness, good wear resistance and chemical
stability.
Non-destructive ultrasonic flaw detection, without sand hole and pore.
Tungsten carbide plate is sintered by HIP-sinter furnace, greatly reduce
porosity, enhance compactness.
Effectively prevent the occurrence of pressing defects by isostatic
pressing machine, and the density is more uniform for cemented carbide
plate blanks.
Stress released, avoid the occurrence of cracks in the cutting and forming
process.

Production technics
Carbide plates are mainly made from wolfram carbide and cobalt powder by powder metallurgy methods. The main production process of sintered tungsten carbide plate is powder milling, ball milling, pressing and sintering. For different uses, the content of WC and Co in tungsten carbide sheet metal is not the same.

Application
Tungsten carbide sheet plate is mainly used to make high-speed die and multi-station progressive die for punching copper, aluminum, stainless steel, cold-rolled sheet, EI sheet, SPCC, silicon steel sheet, hardware, standard parts, upper and lower punches, etc. It is also an excellent material for making high-temperature resistance parts, wear-resistant parts, anti-shielding parts, anti-radiation, and corrosion-resistant parts.

Main Process flow
Powder milling→ formula according to application requirements → wet milling → mixing → crushing → drying → sieving → adding forming agent → redrying → sieving to obtain cemented carbide powder→ granulating → pressing → forming → low-pressure sintering →blanks→Flaw inspection→Packing→Warehousing
