Selection of Sheet Metal Processing Materials

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, frosted 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.

Cold rolled steel SPCC, primarily used for electroplating and baking paint parts, cost-effective, easy to form, material thickness ≤ 3.2mm.

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

3. Galvanized steel sheets SECC, SGCC. SECC electrolytic plates are categorized into N material and P material, with N material primarily not undergoing surface treatment, being more expensive, and P material used for spraying parts.

4. Copper; primarily used for conductive components, surface treatment includes nickel plating, chrome plating, or no treatment, with high costs.

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; complex cross-sectional pieces, widely used in various junction boxes. Surface treatment similar to aluminum sheets.

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