FIELD: metallurgy.
SUBSTANCE: mix material is prepared containing powders of copper and cadmium with the solution of thermally unstable cadmium salt. Said mix is dried and thermally treated at 300-500°C. Produced burden is subjected to cold briquetting and sintering. Then second compaction and annealing are performed to produce Cu-Cd/CdO.
EFFECT: lower wear in current switching, lower junction resistance on operated contacts and higher hardness.
