Before revision: Disadvantages Some disadvantages and problems of cold working are: The metal is harder, calling for greater forces, harder tools and dies, and heavier equipment The metal is less ductile and malleable, limiting the amount of deformation that can be obtained Metal surfaces must be clean and scale-free May leave undesirable anisotropy in the final piece May leave undesirable residual stress in the final piece The need for heavier and equipment and harder tools may make cold working suitable only for large volume manufacturing industry.
