Tungsten carbide cold heading dies are high-hardness, high-strength alloy materials that are pressed and sintered by powder metallurgy methods, and are widely used in the field of production and processing. Under the wear-resistant working conditions of impact or strong impact, the common feature of cold heading dies is that tungsten carbide has good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance. Tungsten carbide cold heading dies are mainly used for: molding and stamping of various metal and non-metallic powders, stretching of steel bars and steel pipes with large compression ratios, forehead forging, perforation and stamping dies that work under large stress, and machine parts , mold cores, making stamping dies, such as stamping watch parts, musical instrument springs, etc.; dies for punching battery shells and toothpaste skins; stamping dies for small-sized steel balls, screws and nuts, impact-resistant forging dies and making standard parts, Cold heading, cold punching and cold pressing dies for bearings, tools and other industries; stamping dies for bullets and bullet casings.
Carbide cold heading dies are widely used, that many things in our daliy life are use these dies to produce. Cold heading dies require die materials with high strength, toughness and wear resistance. Medium and high cobalt and medium and coarse grain size grades are usually be selected. Therefore, when selecting alloy grades, it is necessary to meet specific application requirements according to the processing object and processing working conditions.
