tungsten carbide plate
Performance features
- Excellent red hardness, high hardness, good wear resistance, and chemical
stability. - Non-destructive ultrasonic flaw detection, without sand holes and pores.
- Tungsten carbide plate is sintered by sinter-HIP furnace, greatly reduces
porosity, and enhances compactness. - Effectively prevent the occurrence of pressing defects by cold isostatic
pressing machine, and the density is more uniform for cemented carbide
plate blanks. - Stress released, avoids 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 processes of sintered tungsten carbide plate are 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
