Cemented Carbides International Tungsten Industry ...

Partner In Compounds. Cemented carbides, or hardmetals as they are often called, are materials made by "cementing" very hard tungsten monocarbide (WC) grains in a binder matrix of a tough cobalt or nickel alloy by liquid phase sintering. Cemented carbides combine the high hardness and strength of metallic carbides (WC, TiC, TaC) or carbonitrides ...

Cemented Tungsten Carbides ScienceDirect

The advent of cemented carbides or hard metals began with the idea of replacing costly diamond wire drawing dies for tungsten filaments. This group of sintered materials (WC–Co) had outstanding properties of high levels of hardness and wear resistance. After the application of cemented carbides in drawing dies, attention was drawn to better cutting ...
