The process comprises sintering very fine tungsten powder mixed in the cold with a metallic binder occurring in the liquid state at the sintering temperature. This metallic binder is constituted by a very fine powder, of a granulometry of the order of several microns, containing 65 to 90% of nickel, 5 to 20% of chromium and 5 to 15% of phosphorus, the phosphorus being introduced in the form of an alloy powder containing one at least of the two other binder constituents. |
