Tungsten carbide has a series of excellent properties such as high hardness, good strength and toughnes, and heat resistance. Particularly, its high hardness and wear resistance remain basically unchanged even at a temperature of 500°C, and it still has a high hardness at 800°C.
Cemented carbide is known as the "industrial teeth" and is used to manufacture cutting tools, knives,drilling tools and wear-resistant parts. It is used in military industry, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields.
Tungsten carbide tube expanding bullet is the important accessory of expansion tube process,which has been widely used in the production of heat exchangers and evaporators in the refrigeration industry.
