What are the domestic cemented carbide manufacturers?

Domestic cemented carbide manufacturers are divided into two production bases, Zhuzhou in Hunan and Zigong in Sichuan.

Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance remain basically unchanged even at 500℃, and it still has high hardness at 1000℃.

Cemented carbide is widely used as tool material, such as turning tool, milling cutter, planer, drill bit, boring tool and so on. They are used for cutting cast iron, nonferrous metals, plastics, chemical fibers, graphite, glass, stones and ordinary steel, and can also be used for cutting heat-resistant steel, stainless steel, high manganese steel and tool steel.

China cemented carbide market

According to the data provided by cemented carbide branch of China Tungsten Industry Association, in 20 1 1 year, there were more than 300 cemented carbide manufacturers and 30 professional research institutes in China, with more than 25,000 employees in the whole industry.

By the end of 20 1 1, it has tungsten concentrate 1000000 t/a, tungstic acid and tungsten salt 18000 t/a, tungsten carbide 62000 t/a, cemented carbide 38000 t/a, cobalt, nickel and tantalum.

20 1 1 year, the output of cemented carbide in China is 23,500 tons, the sales income of cemented carbide industry is 20.9 billion yuan, and cemented carbide exports are nearly 5,000 tons, earning more than 360 million US dollars. The output of cemented carbide deep processing products reached 6600 tons, accounting for 1/3 of the total alloy output. The varieties of cemented carbide products produced are basically complete, with more than 40 thousand specifications and models, and the output and varieties can basically meet the needs of various economic fields in China.
