High-density non-magnetic steel counterweight part and manufacturing method thereof

The invention discloses a high-density non-magnetic steel counterweight part and a manufacturing method of the high-density non-magnetic steel counterweight part. The high-density non-magnetic steel counterweight part comprises, by mass percentage, 6-10% of WC powder, 10% of phosphor copper powder, 15-25% of electrolytic pure copper powder, 1% of a stearic acid lithium lubricant and the balance Fe-Mn-C prealloyed powder. The manufacturing method of the high-density non-magnetic steel counterweight part includes the following steps that (1), the components are weighed according to the mass percentage and uniformly mixed in a mixing machine; (2), the mixed powder uniformly mixed is pressed and formed; and (3), high temperature sintering is performed. The manufacturing method is simple in process, controllable in cost, near-net formed and controllable in dimensional change, and the high-density non-magnetic steel counterweight part with the density of 7.7-7.9 g/cm is manufactured. 本发明公开了种高密度无磁钢平衡块零件及其制备方法。以质量百分比
