The lifespan of cemented carbide molds is dozens of times that of steel molds. Cemented carbide molds have high hardness, high strength, corrosion resistance, high temperature resistance and small expansion coefficient. They are generally made of tungsten-cobalt cemented carbide.
Cemented carbide molds have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C, and still have a high hardness at 1000°C.
Carbide molds are widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. They can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult-to-process materials.
Carbide dies have high hardness, strength, wear resistance and corrosion resistance, and are known as “industrial teeth”. They are used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts. They are widely used in military industry, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields. With the development of downstream industries, the market demand for cemented carbide continues to increase. In addition, the future high-tech weapons and equipment manufacturing, the progress of cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for cemented carbide products with high technology content and high quality stability.
Cemented carbide molds can be divided into four categories according to their uses:
One type is cemented carbide wire drawing dies, which account for the vast majority of cemented carbide dies. The main brands of wire drawing dies in my country are YG8, YG6, and YG3, followed by YG15, YG6X, and YG3X. Some new brands have been developed, such as the new brand YL for high-speed wire drawing, and the wire drawing die brands CS05 (YLO.5), CG20 (YL20), CG40 (YL30) and K10, ZK20/ZK30 introduced from abroad.
The second type of cemented carbide dies are cold heading dies and shaping dies. The main brands are YC20C, YG20, YG15, CT35, YJT30 and MO15.
The third type of cemented carbide molds are non-magnetic alloy molds used for the production of magnetic materials, such as YSN in the YSN series (including 20, 25, 30, 35, 40) and steel-bonded non-magnetic mold grade TMF.
The fourth type of cemented carbide mold is a hot working mold. There is no standard grade for this type of alloy yet, and the market demand is increasing.
