Material selection for sheet metal processing
The materials generally used in sheet metal processing include cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum sheet (6061, 5052, 1010, 1060, 6063, hard aluminum, etc.), stainless steel (mirror, brushed, matte), and different materials are selected according to the different functions of the products. Generally, it is necessary to consider the purpose and cost of the products.
1. Cold-rolled sheet SPCC, mainly electroplated and painted parts, low cost, easy to form, material thickness ≤3.2mm.
2. Hot-rolled sheet SHCC, material T≥3.0mm, also electroplated, painted parts, low cost, but difficult to form, mainly flat parts.
3. Galvanized sheet SECC, SGCC. SECC electrolytic sheet is divided into N material and P material. N material is mainly not surface treated and has high cost. P material is used for spraying parts.
4. Copper; mainly used for conductive materials, its surface treatment is nickel plating, chrome plating, or no treatment, high cost.
5. Aluminum plate; generally uses surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6. Aluminum profile; 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.
