In normal use, heavy duty motors can generate heat which will soften the copper. Therefore, to increase the resistance to softening, some silver content according to international standard specifications must be added. Silver is an element when alloyed with copper has the least effect on copper’s conductivity.

We use the right material – OC can cast our own silver bearing copper (CuAg) billets in our own induction furnace. Due to the powerful stirring features of our induction furnace, we can control the precise silver content and assure consistent homogenization.

For Commutators segments, the tolerance of each segment must be strictly controlled, because this is part of a high-speed rotating device. Balance and vibration are critical factors in the assembly of Commutators. OC has vast experience in producing exact uniform segments within fine tolerances according to customer’s specifications.
