Tungsten carbide cobalt properties and application
The hardness of tungsten carbide cobalt (WCCo) is influenced by WC grain size and cobalt content. Tungsten carbide cobalt (WCCO) is an alloy of a hard ceramic phase, the tungsten carbide (WC) and a ductile metallic phase, the cobalt (Co).
Important properties of WCCo are hardness, strength, high breaking and beating ductility as well as high electrical and thermal conductivity. By varying the metallic cobalt content and the tungsten carbide grain size, important properties of the alloy can be specifically adapted. By varying the cobalt content between 0 and 20 mass per cent, hard metals can cover a hardness range from tempered steel to super-hard alloys. The smaller the carbide grain the harder an object can penetrate the surface and the higher is its hardness.
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.
