Tungsten carbide cobalt is an alloy of a hard ceramic phase, the tungsten carbide (WC) and a ductile metallic phase, the cobalt (Co). Hard metals such as WC-Co are non-natural materials not occurring in nature. They are produced by mixing carbide and metal powders, a forming step and a thermal treatment (sintering).

From hard metals, mainly tools are produced for chipping (turning, milling, drilling) or non-chipping shaping (drawing, rolling, spinning), as well as for cutting (stamping) or breaking of metals, wood, paper, plastic, stone, and coal. Further, surgery equipment is produced from WC-Co.

Tungsten cobalt carbide’s trademark is composed by "YG" (the first letter of word “hard and Co” in Chinese) and the average percentage of cobalt content. For example, YG8, the composition of Co is 8%, the rest is tungsten carbide.

Tungsten Carbide exhibits high compressive strength, resists deflection, and retains its hardness values at high temperatures.

Main Properties of Tungsten Carbide

• Excellent Hardness: 86~93 HRA, which equal to 68~81HRC;
• Excellent hot working performance: Hardness could be remained at 60 HRC under 900~1000 ℃
• Excellent wear resistance;
• High cutting speed;
• Long service life;

Tungsten Carbide are widely used as tool materials, such as turning, milling, planer, drill, boring tool for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to machine materials. New carbide cutting tools, the cutting speed is hundreds of times equal to the carbon steel.
