The powder metallurgy is the only technology that allows the production of hard metal raw materials consist of particles of compounds with high purity and controlled particle size, obtained from their ores with an appropriate sequence of chemical processes and temperature. Since ammonium paratungstate (APT) is obtained by reduction in hydrogen tungsten metal, and when must appear in the formulation elements such as titanium, tantalum and niobium, the same are used in the form of oxides.

Sintering is a thermal treatment of a compact of powder below the melting point of the main component. It is used to construct materials with properties that would not have if they were created by other techniques. Instead of "particular" the raw materials (metal and polymer) as a liquid in a mold can be made of a sintering starting from small solid particles, powders, which are welded together by means of temperature increase in special ovens. The mixture, more or less qualitative (and therefore expensive) base consists of dust present in greater quantities, by lubricants and iron powders used to increase the physical, chemical and mechanical properties of the finished product. The temperature must be reached to get the process of sintering is about 0.7 and 0.9 times the melting temperature.The procedure is to remove the porosity between the particles of starting powder, in the growth of particles in the formation of strong links between these and the withdrawal of the components. The characteristic of a component made by sintering is the extreme hardness of the work surface, combined with the relatively cheap in mass-produce it. The carbides are materials consisting of grains with each phase nature of sintered ceramics, carbons, consisting of very hard and extremely fragile, whose representative is the most common carbide WC, and a metallic phase (solid solution, quantitatively minority) with high hardness toughness but limited, consisting of transition metals, usually cobalt, acting as a binder and which has the task of redistributing the mechanical stresses inside the skeleton of the carbides. The hard metal composite structure, which has no counterpart in nature, provides the designer with a combination of properties that no other material can offer, and that is very high hardness accompanied by moderate toughness.
