Forged copper and bronze products are available in plate, block, rounds, discs, bars, rings and tubes. We supply specialty copper alloy forgings for plastic mold tooling and resistance welding applications. To produce a rolled ring, a preform is made by upsetting and piercing a hole on center. This preform is then placed on a ring mill and, through radial and axial pressure, is opened up to desired dimensions. The forging process produces rings with controlled grain flow, which gives strength and resistance to impact and fatigue.
