Compare over 30 copper, brass, and bronze alloys to find the right material for you—all with material certificates for traceability.
Ultra-Conductive 101 Copper Rods
The purest, most conductive copper we offer, with at least 99.95% copper content. Since there’s virtually no oxygen to outgas, it won’t break high-vacuum systems. It also won’t contaminate clean rooms, such as in semiconductor manufacturing.
