Carbide wire drawing die
The hardness of the cemented carbide mold is low, the quality of the wire drawn by the cemented carbide mold is high, and the surface roughness is low, but the wear resistance of the cemented carbide mold is poor, and the service life of the mold is short.
The cemented carbide mold is made of cemented carbide. Cemented carbide is a tungsten-cobalt alloy whose main components are tungsten carbide and diamond. Tungsten carbide is the "skeleton" of the alloy, which is mainly used for hard wear resistance; cobalt is a bond metal and is a source of alloy toughness. Therefore, the cemented carbide mold has the following characteristics compared with the alloy steel mold: high wear resistance, good polishing property, small adhesion, low friction coefficient, low energy consumption, high corrosion resistance, and these characteristics make the brushed carbide The mold has a wide range of processing adaptability and has become the most widely used drawing die.
