About Cemented Carbide (II)

1.The main properties and application

Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C , It still has high hardness at 1000℃. Cemented carbide is widely used as cemented carbide 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. It is used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel, and tool steel. The cutting speed of new cemented carbide tools is now hundreds of times that of carbon steel.


 2.The other special application

Cemented carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasive tools, cylinder linings, precision bearings, nozzles, etc. Most of these above products can be provided by Nanchang Cemented Carbide Factory.


3.The development of cemented carbide

In the past two decades, coated cemented carbide has also come out. In 1969, Sweden (many cemented carbide factories) successfully developed titanium carbide coated tools. The matrix of cemented carbide tools is tungsten-titanium-cobalt cemented carbide or tungsten-cobalt cemented carbide. The thickness of the surface titanium carbide coating is only a few microns. But compared with cemented carbide tools of the same brand, the service life is extended by 3 times, and the cutting speed is increased by 25% to 50%. The fourth generation of coated tools appeared in the 1970s, which can be used to cut difficult-to-machine materials.


4.An example of cemented carbide manufacturer

Nanchang Cemented Carbide Limited Liability Company (NCC for short) as a large state-owned company, it has a complete industrial chain from tungsten raw materials to terminal milling tools. It mainly produces three series of products, tungsten powder products, cemented carbide rods &othe non-standard shape and precision milling tools. Drawing and sample production and processing of various cemented carbide products. NCC is the first lot to meet international quality standards, and its products are both sold well at home and abroad, and are well received by new and old customers!
