Cold Reduction

Cold reduction reduces the thickness of a metal while it is at ambient temperature to achieve a desired mechanical property such as strength or hardness or dimensional property such as thickness or surface finish. Cold reduction is usually done to coiled material on rolling mills. Cold reduction is a form of cold working. Since the reduction is being done below the recrystallization temperature of the metal, there is a limit to the amount of cold reduction that can be done before the metal becomes brittle.
