material choosing in sheet metal fabrication

Sheet metal processing generally used in a cold rolled material (SPCC), hot-rolled plates (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (6061,5052, 1010,1060,6063, duralumin, etc.), aluminum, stainless steel (mirror, brushed surface, matte), according to the role of different products, use of different materials, which normally takes from product use and cost up to consider it.

1. Cold-rolled plate SPCC, mainly used in electroplating and paint pieces, low cost, easy to shape, material thickness ≤3.2mm.

2. Hot-rolled plates SHCC, material T≥3.0mm, also by electroplating, painting parts, low cost, but it is difficult shape, mainly used flat pieces.

3. Galvanized sheet SECC, SGCC. SECC Electrolytic board sub-N material, P material, N materials mainly without surface treatment, high costs, P materials for painting parts.

4. Copper; main role with conductive materials and parts, the surface treatment is nickel, chrome, with or without treatment, high costs.

5. Aluminum; general use surface chromate (J11-A), oxide (conductive oxidation, chemical oxidation), high cost, there are silver-plated, nickel-plated.

6. Aluminum; sectional structure of complex materials and parts used extensively for a variety of plug box. Surface treatment with aluminum.

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