What materials are used for metal stamping parts?

A process that uses presses and dies to deform or fracture sheet metals such as stainless steel and iron, as well as special-shaped materials, thereby achieving specific shapes and dimensions.

Metal stamping is a forming process that uses presses and dies to plastically deform metal sheets—such as stainless steel, iron, aluminum, and copper—through either shaping or fracture, thereby producing parts with specific shapes and dimensions. This process is also known as sheet-metal forming. The process can be broadly categorized into two main types: separation processes and forming processes. Cold stamping is suitable for processing thin metal sheets at room temperature, while hot stamping is often used to relieve internal stresses in the material.
The stamping industry primarily serves the automotive, aerospace, and home appliance manufacturing sectors, and its development is highly dependent on advancements in equipment technology. In China, the stamping industry exhibits uneven regional development: while the small-scale stamping parts market in southern regions is relatively mature, the industry as a whole faces bottlenecks in key material technologies, die precision, and equipment levels. The implementation of stamping processes requires specialized tools such as simple dies, progressive dies, and compound dies; basic operations include specialized machining procedures like blanking, punching, bending, and deep drawing.
