Application of carbide dies :Cemented carbide wire drawing die as a tool material has been increasingly used for cutting tools, wear-resistant tools, impact-resistant tools, and other products with special purpose. Cemented carbide was first used in stretching mold area and has gone though cast iron mold, alloy steel mold, diamond dies, cemented carbide dies, polycrystalline module die and other developmental stages. With the property of high wear resistance, good polishing performance, low friction coefficient, etc., cemented carbide drawing die has been a substitute of steel mould which is used to stretching steel and non-ferrous metal.
