Hardness indicates a material's ability to resist hard objects pressing into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Commonly used hardness indicators include Brinell hardness, Rockwell har

Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy.Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especial
