FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy of low-alloyed copper-based alloys, and can be used for production of walls of combustion chambers of jet engines, water-cooled molds, heat-resistant wires, contacts, etc. Low-alloyed heat-resistant copper-based alloy contains, wt.%: cobalt 0.10–0.45, chromium 0.10–0.45, silicon 0.10–0.20, magnesium up to 0.05, at least one element selected from a group comprising lithium, cerium, boron, up to 0.08 in total, note here that alloy has structure containing Co2Si and Cr3Si phases. Invention also relates to a heat- and electroconductive article made from said copper alloy, in particular to a rocket engine part.
EFFECT: invention is aimed at creating an alloy with high heat resistance while maintaining heat and electrical conductivity at the level of not less than 80% of copper.
