炭化タングステン・コバルト
Tungsten carbide cobalt Tungsten carbide cobalt cemented carbide is a composite material with tungsten carbide as the hard phase and cobalt as the binder phase. It is classified into three categories based on cobalt content: high cobalt (20%-30%), medium cobalt (10%-15%), and low cobalt (3%-8%). Typical grades produced in China include YG2, YG3, YG3X, YG6, YG8, etc., where “YG” represents “WC-Co,” the suffix number indicates the percentage of cobalt content, and “X” and “C” represent fine-grained and coarse-grained structures, respectively. This material possesses high hardness and bending strength, and is widely used in the manufacture of cutting tools, dies, cobalt tools, and wear-resistant parts. It is extensively applied in military, […]
