How to choose materials for Sheet Metal Processing in Shenyang?

The materials commonly used in sheet metal processing include cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU), brass, purple copper, beryllium copper, aluminum plates (6061, 5052, 1010, 1060, 6063, hard aluminum, etc.), stainless steel (mirror, brushed surface, matte surface). Depending on the product's function, different materials are selected, and the product's purpose and cost should be considered.

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

2. Hot rolled plate SHCC, material T3.0mm, 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; Mainly using conductive materials, the surface treatment is nickel plating, chromium plating, or no treatment, which is costly.

5. Aluminum plate; Generally, surface chromate (J11-A) is used for oxidation (conductive oxidation, chemical oxidation), which is costly. Silver plating and nickel plating are available.

6. Aluminum profiles; Materials with complex cross-sectional structures are 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.

Sheet metal processing is a key technology that sheet metal technicians need to grasp, and it is also an important process for forming sheet metal products. Sheet metal processing includes traditional methods and process parameters such as cutting, punching, and bending forming, as well as various cold stamping die structures and process parameters, equipment working principles and operation methods, and new stamping technologies and processes. The processing of metal sheet parts is called sheet metal processing.
