Selection Of Sheet Metal Materials

With the development of today's society, the sheet metal industry has also developed rapidly. Sheet metal now involves various industries, and for any sheet metal part, it has a certain processing process. To understand the sheet metal processing flow, one must first know the selection of sheet metal materials.

The materials commonly used for sheet metal processing include cold-rolled sheet metal (SPCC), hot-rolled sheet metal (SHCC), galvanized sheet metal (SECC, SGCC), copper (CU), brass, purple copper, beryllium copper, aluminum plates (6061, 6063, hard aluminum, etc.), aluminum profiles, stainless steel (mirror, brushed surface, matte surface). Depending on the product's function, different materials are selected, and the product's purpose and cost generally need to be considered.

1. Cold rolled SPCC sheet is mainly used for electroplating and baking paint parts, with low cost, easy molding, and material thickness≤3.2mm.

2. Hot rolled plate SHCC, material T≥3.0mm, also uses electroplating and baking paint parts, with low cost but difficult to form, mainly using flat parts.

3. Galvanized sheet SECC, SGCC. SECC electrolytic plates are divided into N material and P material. N material is mainly not surface treated and has a high cost, while P material is used for spraying parts.

4. Copper: It is mainly used as a conductive material, and its surface treatment is nickel plating, chromium plating, or no treatment, which is costly.

5. Aluminum plate: Generally, surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating are available.

6. Aluminum profiles: Materials with complex cross-sectional structures, widely used in various plug-in boxes. Surface treatment is the same as aluminum plate.

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