A cartridge for faucets having some parts which are assembled in the cartridge to function as a guide, an element of support for a movable small plate of hard material, forming a part of the above mentioned guiding parts, at least one small plate of hard material operatively mounted and fixed in the cartridge, and at least one movable small plate mounted in the aforementioned element of support and adapted to be movable in relation to the fixed small plate in order to bring about the regulation of fluid flow and the proportion of mixing. At least one of the surfaces of the parts of plastic material, adapted to slide against the surface of other pieces of plastic material, is provided with a metal layer, preferably by chemical or electrochemical means. It is preferred that the metal cover is applied on an intermediate part having surfaces adapted to slide in contact with different parts of plastic material, and precisely on a guiding ring.
