The carbide is a composite formed by tungsten carbide particles (WC) incorporated together by a binder which is usually cobalt (Co).

The production of the hard metal is carried out by powder metallurgy processes.
It starts with the accurate mixing of the WC and Co powders with the addition of a lubricating component (usually paraffin) to promote the uniformity of pressing or extrusion. To allow processing of the extruded or pressed components, these are subjected to a presintering process which determines a consistency similar to that of the chalk used to write on the blackboard. Through the final sintering, the transformation in the desired product is carried out.
