How to choose materials for sheet metal processing

The materials generally used in sheet metal processing are cold rolled plate (SPCC), hot rolled plate (SPH), galvanized plate (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum plate (6061, 6063, Duralumin, etc.), stainless steel (mirror surface, brushed surface, matte surface), depending on the role of the product, the choice of materials is different, and generally need to be considered from the product's use and cost.

1. Cold-rolled sheet SPCC, mainly used for electroplating and baking varnish parts, low cost, easy to shape, material thickness ≤ 3.2mm.

2. Hot-rolled sheet SPH, material T≥3.0mm, also uses electroplating, baking varnish parts, low cost, but difficult to form, mainly flat parts.

3. Galvanized sheet SECC, SGCC. SECC electrolytic board is divided into N material and P material. N material is mainly used for surface treatment and high cost. P material is used for sprayed parts.

4. Copper; mainly uses conductive material, and its surface treatment is nickel plating, chrome plating, or no treatment, which is costly.

5. Aluminum plate; generally use surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.

6. Stainless steel; mainly used without any surface treatment, high cost.
