Materials commonly used in sheet metal processing include cold rolled sheet (SPCC), hot rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (Cu) brass, red copper, beryllium copper, aluminum sheet (6061, 5052, 1010, 1060, 6063, hard aluminum, etc.), stainless steel (mirror, wire drawing surface, fog surface), 1. Cold rolled sheet SPCC, mainly used for electroplating and paint parts, low cost, easy to form, material thickness ≤ 3.2mm. 2. Hot rolled SHCC plate, material t ≥ 3.0mm, is also electroplated and painted parts, with low cost, but difficult to form, mainly 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 mainly uses 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) and oxidation (conductive oxidation and chemical oxidation) are used, with high cost, including silver plating and nickel plating. 6. Aluminum profile; Materials with complex cross-section structure are widely used in various plug-in 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. According to the different functions of products and materials, it is generally necessary to consider the use and cost of products.
