Cemented carbide die toolss are ten times or even dozens of times the life of steel die toolss. Cemented carbide die toolss have only high hardness, high strength, corrosion resistance, high temperature resistance and low expansion coefficient. Generally, tungsten-cobalt cemented carbide is used.
Cemented carbide die toolss 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 are basically not maintained even at a temperature of 500 ℃ Change, still very high hardness at 1000 ℃.
Cemented carbide mould
Cemented carbide die toolss are widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used Cutting difficult-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc.
Cemented carbide die toolss 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, and are widely used in military and aerospace industries. With the development of downstream industries in aviation, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, the market demand for cemented carbide continues to increase. And in the future, the manufacturing of high-tech weapons and equipment, advances in cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for high-tech and high-quality and stable cemented carbide products.
Cemented carbide die toolss can be divided into four categories according to their uses:
One type is cemented carbide wire drawing dies, which occupies most of the cemented carbide dies. The main grades of wire drawing dies in our country are YG8, YG6, YG3, followed by YG15, YG6X, YG3X, and some new grades have been developed, such as the new grade YL for high-speed drawing, and the wire drawing die grade CS05 (YLO. 5) imported from abroad. ), CG20 (YL20), CG40 (YL30); K10, ZK20/ZK30.
The second type of cemented carbide die toolss are cold heading, cold punching and shaping die toolss. The main brands are YC20C, YG20, YG15, CT35, YJT30 and MO15.
The third type of cemented carbide die toolss are non-magnetic alloy die toolss used for the production of magnetic materials, such as YSN of the YSN series (including 20, 25, 30, 35, 40) and steel junction non-magnetic die tools grades TMF.
The fourth type of cemented carbide die toolss are hot work die toolss. There is no standard grade for this type of alloy, and the market demand is increasing.
