Processing technology and application of wire drawing die

The cobalt content of cemented carbide used for wire drawing is low, and the main raw materials are tungsten carbide with the content of 99.95% and a small amount of cobalt.

Hard alloy wire-drawing material has good wear resistance, impact resistance, polishing property and corrosion resistance, and is easy to repair and low in price. It is a commonly used wire-drawing die core material and is widely used in drawing dies for thick and medium wires. By improving the composition and microstructure of cemented carbide, controlling the fluctuation of carbon content and refining carbide particles, the properties of the material can be improved and its service life can be prolonged.
