The invention relates to metallurgical powder. The metallurgical powder comprises, by mass, 1 to 5 parts of graphite powder, 5 to 10 parts of electrolytic copper powder, 2 to 8 parts of stearic acid,5 to 8 parts of nickel oxide, 50 to 98 parts of electrolytic nickel powder, 1 to 5 parts of nanometer manganese sulfide, 5 to 10 parts of nanometer cobalt powder, 5 to 10 parts of nano-sized chromic oxide, 0.2 to 0.5 part of an easily-cut agent, 0.5 to 1 part of nano chromium trioxide and 0.2 to 0.5 part of a reinforcing agent. The pollution of the formula to the environment is small.
