Description
Bronze Brkd1 used: for the manufacture of long products and profile rolling; collectors, electric motors; parts of welding machines; cold-formed profiles used to manufacture the collector plates of electrical machines; compressed (82 mm), drawn (18−40 mm) and rolled (46, 52, 60 mm) bars for the manufacture of elektrodvigatelei, rollers and other parts for resistance welding used in the manufacture of automobiles.
Note
Brkd1 cadmium bronze has a high electrical conductivity and strength at high temperatures.
Analogue of bronze Brkd1 according to ST SEV 377−76 is bronze CuCd1.
