Tungsten carbide dies

Tungsten carbide dies was made of tungsten and cobalt carbide, having dozen times even several ten times longer working time than steel die with advantages of high hardness, high strength, corrosion resistance, high temperature resistance and low expansion coefficient.

Our tungsten carbide dies were used in Hardware fasteners industry, mainly include Cold heading, Cold punching, powder metallurgy, drawing stamping etc.
