Tungsten carbide has a very wide range of applications, appearing in many places. Today, let’s discuss its five most widespread uses.
One reason for the widespread use of tungsten carbide is that the combination of carbon and tungsten produces many unique and excellent properties, such as heat resistance, rust resistance, scratch resistance, corrosion resistance, a hardness second only to diamond, excellent electrical conductivity, and an overall strength three times that of steel. Furthermore, tungsten carbide is easily formed into various shapes, or it can be sprayed onto corresponding metal products.
Hard Alloys
For example, drilling platforms and mining platforms require a lot of hard alloys, and these are where tungsten carbide shines. Currently, about 65% of the world’s tungsten carbide is used in mining drill bits or cutting materials, and a large portion is used in alloys or stainless steel materials reinforced with tungsten carbide spraying.
Industrial Alloys
More than 17% of tungsten carbide is used to create various specialty alloys or composites. These cemented carbides can be combined with nickel, iron, silver, and copper, finding applications in the construction, electronics, industrial gear manufacturing, radiation shielding materials, and aerospace materials manufacturing industries.
Rolling Mill Products
Approximately 10% of tungsten carbide is used to manufacture various rolling mill products, including end mills and rolling mill inserts. These products vary in size and shape depending on the materials they contact and machine, but all are used for grinding and milling. Because tungsten carbide is very hard and easily molded, it can be used to create attachments for precision milling applications, producing coarse-ground materials or the finest powders.
Jewelry
While the above three applications already account for over 90% of tungsten carbide’s annual applications, tungsten carbide products are now expanding into new areas, such as its increasing popularity in the jewelry industry. Tungsten carbide’s hardness makes it suitable for making the metal parts of rings, pendants, earrings, and other jewelry. When properly cut and polished, tungsten carbide is actually quite beautiful and can partially replace gold jewelry.
Surgical Tools
The medical industry is another important application area for tungsten carbide. Typically, the handles of various surgical instruments are made of stainless steel or titanium alloy, while the blades are generally made of tungsten carbide. This utilizes tungsten carbide’s high hardness and wear resistance, effectively extending the lifespan of the surgical instruments.
Of course, besides the five major applications mentioned above, tungsten carbide also has excellent applications in other fields. For example, it is used in sports such as ski poles, skis, and fishing rods, as well as in the cutting and shredding parts of some recycling machines.
