Silver-bearing copper is another quality product of GCAL. The addition of a small amount of silver in the copper improves the resistance to softening of materials. Most applications for this material are commutator bars and segments in traction motor and various industrial DC motors. GCAL can produce silver-bearing copper in many shapes according to customer's requirements.
