Material Selection for Sheet Metal Processing

Sheet metal processing commonly utilizes materials such as cold rolled steel (SPCC), hot rolled steel (SHCC), galvanized steel (SECC, SGCC), copper (CU), brass, bronze, beryllium copper, aluminum plates (6061, 5052, 1010, 1060, 6063, hard aluminum, etc.), and stainless steel (mirror finish, brushed finish, matte finish). The choice of material varies depending on the product's function, and generally, considerations should be made based on the product's purpose and cost.

1. Cold-rolled steel SPCC, primarily used for electroplating and baked paint components, offers low cost, easy molding, and material thickness ≤ 3.2mm.

2. Hot-rolled steel SHCC, material thickness T≥3.0mm, also used for electroplated and baked paint parts. Cost-effective but difficult to shape, mainly used for flat sheet components.

3. Galvanized Sheets: SECC, SGCC. SECC electrolytic plates are categorized into N material and P material. N material is primarily not surface treated, with a higher cost, while P material is used for painted parts.

4. Copper; primarily used for conductive components, with surface treatments such as nickel plating, chrome plating, or no treatment at all, which are costly.

5. Aluminum Sheets; commonly used with surface chromate (J11-A), anodized (conductive anodized, chemical anodized), high cost, with silver plating, nickel plating.

6. Aluminum profiles; pieces with complex cross-sectional structures, extensively used in various junction boxes. Surface treatment is the same as for aluminum sheets.

7. Stainless Steel; primarily used without any surface treatment, high cost.
