Sheet metal is one of the three elements of stamping processing. The performance requirements for electronic hardware stamping parts and electronic stamping parts involve physical properties such as material hardness, tensile strength, and shear strength. Stamping forming process involves stamping cutting, stamping bending, stamping stretching and other related processes. Among numerous metal materials, each material has its own characteristics, and designers generally judge whether this process is suitable for this material based on its characteristics.

When cold rolling carbon steel sheets and strips for electronic hardware stamping parts and electronic stamping materials, they are suitable for products with lower stamping processing degree, such as punching, bending, etc. Steel is suitable for stamping and stretching requirements, as well as for stamping parts with repeated stamping or highly formed SPCE: the tensile performance is higher than SPCD, and the surface needs to be electroplated (this material is used less frequently).

SECC material is equipped with a galvanized layer, which has good anti-corrosion performance. Generally used for stamping appearance parts of electronic hardware stamping parts.

Stainless steel has physical properties such as high hardness, high strength, corrosion resistance, welding performance, and antibacterial properties. Select the appropriate material grade according to the functional requirements of the stamped parts during stamping processing.

Stainless steel 301: It has a relatively low chromium content and poor corrosion resistance, but the material can achieve high tensile strength and hardness after heat treatment, and has good elastic properties. It exhibits obvious work hardening phenomenon during deformation and is used in various situations that require high strength.

Stainless steel 304: The carbon content, strength, and hardness are all lower than SUS301. But the material added has strong corrosion resistance. High strength and hardness can be achieved through heat treatment. Widely used in the production of equipment and components that require good comprehensive performance (corrosion resistance and formability).
