简介：Quality alloy mold the life span of more than ten times that of steel or even dozens of times, hard alloy moulds only high hardness, high strength, corrosion resistance, high temperature resistant and low expansion coefficient, are generally use cobalt tungsten carbide. As the market standard material YG3, YG6, YG6X YG8. YG15, YG20, YG20C, YG25 and HU20 HU222, HWN1 (non-magnetic alloy mold), etc., using native carbide material, low pressure sintering and other special craft, toughness is better than the regular production, life will also improve 3-5 times.
