WebJun 30, 2024 · Here are the three main benefits to annealing: Annealing makes metals more formable. When metal is stronger and more ductile, it gives manufacturers more leeway in the fabrication process. There is less risk of material fracturing from bending or pressing. WebUsually, cold rolling is used after the hot rolling of metal to give the metal a clean and smooth finish. It also increases tensile strength and stiffness. #2. Cold Extrusion: Cold Extrusion is also done by passing the metal stock or piece through the dies by applying a compressive force to change the shape of the metal piece.
