Cold working is a metalworking process that involves deforming a metal at room temperature. This technique enhances the material's strength and hardness through strain hardening, which occurs as the metal's internal structure is altered. Common methods of cold working include rolling, drawing, and forging. During cold working, the metal becomes less ductile, meaning it is less able to be shaped without breaking. This process is widely used in manufacturing to create precise shapes and improve the mechanical properties of metals, making them suitable for various applications in industries such as automotive and construction.
