MANUFACTURED FOR MECHANICAL AND ELECTRICAL APPLICATIONS

Electric Materials manufactures high-quality copper rings for electrical and mechanical applications utilizing the centrifugal casting process. The molten copper is poured into a hollow cylindrical mold, spinning on a vertical axis. The mold spins with a predetermined speed based on its diameter, creating the required centrifugal force. This process places the molten copper under great power and pressure. These controlled conditions create an excellent casting which solidifies from the outside inward, and therefore is free from gas pockets, blowholes, and shrinkage cavities. During the pour, the heavier metal is forced outward, and the lighter oxides and other impurities are displaced to the inside diameter of the casting which can be removed during machining.
