Tungsten carbide (chemical formula: WC) is a compound (specifically, carbide) containing equal numbers of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed into shape by a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing bullets and jewelry.
The tungsten carbide used in the refractory metal products production process of waste, scrap metal, tungsten, tungsten wire, tungsten powder and tungsten oxide, and through cleaning, roasting, reduction, carbonization, adjust and carbide manufacturing process, made of cobalt and tungsten carbide distribution is very uniform, tungsten carbide tungsten cobalt crystallite size 0.6 1.0 um classes or cobalt tungsten titanium carbide or hard alloy spray welding powder.
Tungsten alloy has high strength, hardness, high-temperature resistance, wear resistance and good electrical properties.
It is widely used as cutting tools, wear resistant parts, armor-piercing core, shell warhead, refractory gold and electrical alloy, etc.
At present the main varieties of tungsten alloy are hard alloy, tungsten iron, tungsten rod (tube), tungsten wire, tungsten sheet, high specific gravity alloy and tungsten chemical materials, etc.
