In the paper, the research and development of tungsten heavy alloy at home and abroad in recent years were overviewed systemically from raw materials, sintering process and its subsequent treatment, strengthening-toughening treatment, the influence of impurities etc respectively. The concrete factors which influence property of tungsten heavy alloy were discussed in detail. And some ideas about the orientation of tungsten heavy alloy in the future were put forward.
