JL50 tungsten carbide drawing dies and YG20 Carbide drawing dies as primarily for the manufacture of stamping dies, such as stamping watch parts, strings and other musical instruments, red battery shell mold toothpaste, small balls, screws and other stamping dies. Hardness of not less than 85HRA. Density 13.8g/mm ³ to 14.2 g / mm ³, bending strength is about 2300MPa. Have a certain shape of the hole all centers, round, square, octagonal, or other special shapes. Has a strong compressive pressure can be used. Carbide brittle nature, can not guarantee that it does not break. Therefore, extreme caution when handling. As a high-quality carbide core, with high hardness, good thermal conductivity, low coefficient of friction characteristics.
