Powder metallurgy material for manufacturing high-density part and processing technology thereof

The invention relates to a powder metallurgy material for manufacturing a high-density part and a processing technology thereof. A powder metallurgy iron-based alloy is prepared from the following raw materials in percentage by weight: 0.2-0.3% of C, 0.2-0.6% of P, 0-4% of Cu, 0-0.5% of Mo and balance of Fe. The processing technology of the powder metallurgy material for manufacturing the high-density part comprises the following steps: uniformly mixing powder metallurgy raw materials in a mixer, and then pressing and moulding by adopting a powder metallurgy press, wherein density of a pressed green body is 7.2-7.25g/cm ; carrying out high temperature sintering for 30-40 minutes at a sintering temperature of 1120-1200 DEG C; carrying out mechanical processing, so that a powder metallurgy part with the density of 7.2-7.4g/cm is obtained. The powder metallurgy material for manufacturing the high-density part has the advantages that sintering expansion, caused by copper, of the part is inhibited by adjusting car
