As for the introduction of the use of tungsten carbide, it has been introduced before by Harris of Taizhou. Its application scope is too wide, and it has been involved in many places. Today, let's discuss the five most widely used uses of WC.
Tungsten carbide is widely used on the premise that the combination of carbon and tungsten can produce many unique and excellent characteristics, such as heat-resistant, rust proof, scratch proof and corrosion-resistant. Its hardness can be second only to diamond, but also has excellent conductivity. At the same time, its overall strength can reach three times of that of steel. Moreover, tungsten carbide is also easy to form, can be processed into various shapes, or carbon can be used. The alloy is sprayed on the corresponding metal products in the way of tungsten carbide spraying.
For example, the drilling platform or mining platform needs a lot of cemented carbide. These are places where tungsten carbide can make great achievements. At present, about 65% of the world's tungsten carbide is applied to mining bits or cutting materials, and most of them are alloy or stainless steel materials strengthened by tungsten carbide spraying.
More than 17% of WC materials will be used to make various special alloys or composites. These cemented carbides can be combined with nickel, iron, silver and copper, and can be used in construction industry, electronic industry, industrial gear manufacturing, radiation shielding materials and aviation industry materials manufacturing industries.
Rolling mill products
About 10% of tungsten carbide is also used to manufacture various mill products, including various end mills and mill blades. These products vary in size and shape depending on the materials they touch and process, but all products are used for grinding and milling. Since WC is very hard and easy to mold, accessories can be created for precision milling applications to produce raw materials or the finest powders.
These three kinds of application places have accounted for more than 90% of tungsten carbide applications every year, but now tungsten carbide products have expanded new fields, such as jewelry industry is more and more popular. The hardness of tungsten carbide makes it suitable for making metal parts of rings, pendants, earrings and other jewelry. After the correct cutting and polishing, the tungsten carbide material is actually very beautiful, which can partially replace the gold jewelry products.
At present, the medical industry is another important application field of tungsten carbide. In general, the cutter bars of various surgical cutters are made of stainless steel or titanium alloy, while the blade parts are generally made of tungsten carbide, which takes advantage of the characteristics of high hardness and wear resistance of tungsten carbide, and can effectively extend the service life of surgical cutters.
Of course, in addition to the above five applications, tungsten carbide also has very good applications in other fields, such as ski poles, skis, fishing rods in the field of sports, as well as the cutting and crushing parts of some recycling machines, which will use tungsten carbide.
