hårdmetall
Hårdmetall is a sintered composite material, primarily composed of a hard carbide compound mixed with a binder metal. The most common type of hardmetall uses tungsten carbide (WC) as the hard phase, bound together by cobalt (Co). Other carbides, such as titanium carbide (TiC) and tantalum carbide (TaC), can be added to modify the properties. The binder metal can also vary, with nickel (Ni) sometimes used, particularly for applications requiring corrosion resistance.
The production process involves mixing fine powders of the carbide and binder metal, followed by pressing the
Hårdmetall possesses exceptional hardness, wear resistance, and compressive strength, while exhibiting relatively low tensile strength and
