Comparison of Cemented Carbide Grades

Cemented carbide is a material made largely from tungsten carbide and a binder. The choice of material will depend on the specifics of the application and its technical demands. With our many years of experience and the extensive know-ledge possessed by our applications technicians and engineers we are always in a position to make up the right component for you, at maximum precision. A cemented carbide is a composite material comprised of individual tungsten carbide grains imbedded in a ductile metal binder matrix of either cobalt or nickel. The physical and metallurgical properties of a particular "grade" of carbide are determined by its composition (its constituents and their relative amounts), the size distribution of the tungsten carbide grains after sintering, the binder metal type and content, the quality of the raw materials used, and the workmanship with which the material is made. Those most commonly measured to assess quality and define application areas are described below. The ASTM and/or ISO standard that applies to each of these measurements is also noted. Density or specific gravity is the weight per unit volume of a cemented carbide measured in grams per cubic centimeter (g/cm3). It is essentially the weighted average of the densities of all of the components contained in the product and is therefore a check on its composition. For grades containing only tungsten carbide and a binder metal, the density of the composite decreases as the lighter binder metal content increases.
