FIELD: electrical industry; home appliance manufacturing. SUBSTANCE: copper melt is produced of copper and alloying components taken in the amount sufficient to yield 15-35% (by volume) of β-phase. Then castings are poured, followed by hot molding, drawing with intermediate annealings at temperatures 100-200 C higher than the recrystallization temperature and with last stage deformation ratio of 20-25% followed with cold upsetting. EFFECT: increased efficiency of the process. 4 cl, 1 tbl
