FIELD: production of powder materials based on copper. SUBSTANCE: method for production of powder materials based on copper includes grinding of chips of iron-aluminium bronze and its screening, preparation of charge, molding of porous blank, its sintering and repeated finishing-compaction. Chips BR A9Zh4 are ground in attritor for 1-5 h with ball-to-chips ratio of 6-48, and introduced into charge is 1-15 mas.% of ground chips of fraction sizing 10-316 mcm. EFFECT: higher efficiency.
