Cemented carbide pressing is a hard and highly wear-resistant material made by mixing metal powder (usually tungsten-cobalt or tungsten-titanium carbon, etc.) with a certain amount of binder, and then pressing and sintering. Cemented carbide has the characteristics of excellent wear resistance, corrosion resistance, high temperature strength and deformation resistance, and is widely used in machining, mining drilling, cutting tools, automobile manufacturing and other fields.
The pressing of cemented carbide products mainly includes two methods: cold pressing and hot pressing. Cold pressing is to press and form metal powder and binder at room temperature, and the pressed blank needs to be heat treated to meet the performance requirements of cemented carbide. Hot pressing is to press the metal powder and binder into shape at high temperature,
which further improves the density and hardness of the cemented carbide body, shortens the heat treatment time, and can inject elements required for the strength and toughness of the material during the manufacturing process. , to improve the performance of cemented carbide.
