Tungsten Carbide
 

We can custom make special parts in these materials (hard metals), custom made, with very high precision and the best finishing. We are able to realize miniaturized parts, very very small (almost invisible) and with very very small holes, few mm/100. See the table for the usual hard metals, other ones can be supplied on request.
