Performance Characteristics Of Cemented Carbide
Jul 26, 2018

High hardness (86~93hra, equivalent to 69~81HRC);

Thermal rigidity good (up to 900~1000℃, keep 60HRC);

Good wear resistance. Carbide cutting tool is higher than high speed steel cutting speed 4~7 times, tool life is high 5~80 times. Manufacturing molds, measuring tools, life than alloy tool steel high 20~150 times.

Can be cut around 50HRC of hard material. But hard alloy brittle, can not be cut, difficult to make a complex shape of the whole tool, so often made into different shapes of blades, using welding, bonding, mechanical clamping and other methods installed in the knife body or mold body to use.
