Commutator Copper

Commutators are electrical components for which the advantages of oxygen-free copper can be fully exploited, and OF copper has quickly become the industry standard.

Oxygen-free copper is the purest form of the metal and offers unparalleled thermal and electrical conductivity as well as superior weldability. As a conductor, it generates much less internal heat than other copper grades and it suffers a much lower decrease in conductivity at high temperatures. A small amount of silver alloyed in copper increases the softening temperature of pure copper without any major sacrifice in electrical conductivity.

Our commutator strips, profiles and wires are manufactured in the full range of oxygen-free silver bearing copper grades.
