The tungsten carbide powder is classified according to its average particle size range, and is divided into 16 grades. The classification methods and principles are as follows:
In 2019, the national standard version of tungsten carbide powder (standard status: current) used tungsten carbide powder to produce cemented carbide and other powder metallurgy products with an average particle size of not less than 0.6um tungsten carbide powder is divided into 18 grades: according to its average particle size range, tungsten carbide powder is divided into 18 grades: FWC06-07, FWC07-08, FWC08-10, FWC10-15, FWC15-20, FWC20-25, FWC25-30, FWC30-40, FWC40-50, FWC50-60, FWC60-80, FWC80-100, FWC100-150, FWC150-600, FWC200-250, FWC250-300, FWC300-350, and FWC350-450. Examples of their expression methods are as follows:
FWC50~60:
FWC refers to tungsten carbide powder.
50~60 refers to the particle size 5~6um
