Common materials 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.), aluminum profile, stainless steel (mirror, drawing surface, fog surface). According to the different functions of the product, choose different materials, generally consider the use and cost of the product.
1. Cold rolled plate SPCC is mainly made of electroplated and painted parts with low cost, easy forming and material thickness less than or equal to 3.2mm.
2. Hot rolled plate SHCC, material t ≥ 3.0 mm, can also be used for electroplating, paint parts, low cost, but forming difficult, first use flat parts.
3. Galvanized sheet SECC, State Grid Corporation of China. SECC electrolytic plate is divided into n material and P material. N material is not used for surface treatment, and the cost is high. P material is used for spraying parts.
4. Copper; mainly used for conductive materials, its surface treatment for nickel, chromium, or without treatment, high cost.
5. Aluminum plate; generally used for surface chromate (j11-a), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6. Aluminum profiles; materials with complex cross-section structure, many of which are used for various plug boxes. The surface treatment is the same as that of aluminum plate.
7. Stainless steel; mainly used without any surface treatment, high cost.
