ABSTRACT:
The finished metallic material of this invention is constituted by an agglomerate of finely divided metallic powder, the grains of which are bonded together by means of an organic substance, the volume of such substance being comprised between 0.5 and 7% of the total volume of the material. In order to obtain said material, the metallic powder is mixed with the organic substance, the mixture is moulded under high pressure and after removal from the mould, the material is heated in order to harden the organic substance. The material is employed to advantage for elements constituting horological articles.
