摘要
A fabrication method for a tungsten heavy alloy includes first fabricating a green compact or a sintered body composed of tungsten and other elements except manganese, then putting manganese thereon, and sintering the tungsten heavy alloy with manganese manganese, whereby the formation of pores, which occurs because manganese is oxidized by the deoxidation of oxides existing on the surface of powders of tungsten, nickel and iron is prevented, and a tungsten heavy alloy having a 100% non-theoretical density of 100% is obtained.
