     Cold forging is a technical process for forming and forging profiles at room temperature. Cold forging materials are mostly aluminum and some alloys, copper and some alloys with low deformation resistance and good plasticity at room temperature. Cold forging can produce work hardening during the processing of profiles and increase the strength and hardness.
