FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly it relates dispersion-rein-forced composite on the basis of copper. It can be used for manufacturing of contact welding electrodes and sliding contacts, operating with high loadings. Composite contains, wt %: aluminium 0.15-0.60; oxygen 0.14-0.55; carbon 0.04-0.14; copper - the rest.
EFFECT: high-conductivity and plasticity with keeping of durability, solidity and heat resistance.
