Classification by usage
Cemented carbide has a series of excellent properties and is widely used. With the passage of time, its use is expanding. The main uses are as follows:
cemented carbide can be used as a variety of cutting tools. The cemented carbide consumption of cutting tools in China accounts for about one third of the total cemented carbide output (about 3000 tons), of which about 78% are used for welding tools and about 22% are used for indexable tools. The cemented carbide used for numerical control tools only accounts for about 20% of the cemented carbide used for indexable tools. In addition, there are cutting tools such as integral cemented carbide drill bits, integral cemented carbide small circular saw blades, and cemented carbide micro drills.
Geological mining tools
geological mining tools are also a major use of cemented carbide. Cemented carbide for mining in China accounts for about 25% of the total production of cemented carbide. It is mainly used for drill bits for impact drilling, bits for geological exploration, down the hole drills for mines and oil fields, roller drills, coal cutter picks, impact drills for building materials industry, etc.
cemented carbide used as various molds accounts for about 8% of the total production of cemented carbide, including wire drawing dies, cold heading dies, cold extrusion dies, hot extrusion dies, hot forging dies, forming dies, and drawing tube mandrels, such as long mandrels, spherical mandrels, floating mandrels, etc. in recent decades, the consumption of various cemented carbide rolls used for rolling wire materials has increased rapidly, and the cemented carbide used for rolls in China has accounted for 3% of the total production of cemented carbide.
there are many products made of cemented carbide for structural parts, such as rotating seal rings, compressor pistons, lathe chucks, grinder spindles, bearing journals, etc.
Wear resistant parts
wear resistant parts made of cemented carbide include nozzles, guide rails, plungers, balls, tire anti-skid nails, snow shovel plates, etc.
Cavity for high pressure and high temperature resistance: the most important use is to produce top hammer, cylinder and other products for synthetic diamond. Cemented carbide for top hammer and cylinder has accounted for 9% of the total cemented carbide production in China.
cemented carbide is used more and more widely, and has been expanding in the civil field in recent years, such as watch chain, watch case, zipper head of high-grade luggage, cemented carbide trademark, etc.
