Abstract

The object of the invention is to provide a weight made of a tungsten based sintered alloy having desired oxidation resistance without depending on Ni plating and coating treatment technology for oxidation prevention and further without performing these treatments, and free from corrosion. To achieve the object, the weight made of a tungsten based sintered alloy has a composition comprising, as bonding phase forming components, by mass, 0.5 to 7% Ni, 0.5 to 4% Mo and 0.1 to 1.0% Cr, and the balance W with inevitable impurities, and has a specific gravity of 17 to 19. Alternatively, the weight made of a tungsten based sintered alloy has a composition comprising, as bonding phase forming components, 0.5 to 7% Ni, 0.5 to 4% Mo, 0.1 to 1.0% Cr and 0.5 to 3.0% Fe, and the balance W with inevitable impurities, and has a specific gravity of 17 to 19. Alternatively, in the weight made of a tungsten based sintered alloy, as the inevitable impurities, preferably, Cu is not contained by ≥ 1%.
