Precision sheet metal

Selection of sheet metal processing materials

The materials commonly used in sheet metal processing include cold rolled plate (SPCC), hot rolled plate (SHCC), galvanized plate (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum plate (6061, 5052, 1010, 1060, 6063, duralumin, etc.

1. Cold rolled sheet SPCC, mainly used for electroplating and baking, has low cost, is easy to form, and the material thickness is ≤ 3.2mm.

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

3. Galvanized sheet SECC, SGCC. SECC electrolytic plate is divided into N material and P material. N material is mainly not subject to surface treatment, and the cost is high. P material is used for spraying parts.

4. Copper; It is mainly used for conductive materials, and its surface treatment is nickel plating, chromium plating, or no treatment, with high cost.

5. Aluminum plate; Generally, surface chromate (J11-A) is used for oxidation (conductive oxidation, chemical oxidation), with high cost, including silver plating and nickel plating.

6. Aluminum profile; The materials with complex section structure are widely used in various boxes. The surface treatment is the same as that of aluminum plate.

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