According to the product function is different, the choice of materials is different, generally need to consider its use and cost from the product.
1. Cold rolled plate SPCC, mainly with electroplating and baking parts, low cost, easy to shape, material thickness ≤3.2mm.
2. Hot rolled plate SHCC, material T≥3.0mm, also with electroplating, paint, low cost, but difficult to shape, mainly with flat parts.
3. Galvanized sheet SECC, SGCC. SECC electrolytic plate is divided into N material, P material, N material is mainly not for surface treatment, high cost, P material is used for spraying parts.
4. Copper; Mainly electrically conductive materials, the surface treatment is nickel plating, chromium plating, or no treatment, high cost.
5. Aluminum plate; Generally used surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6. Lu: xingcai; Materials with complex cross section structure are widely used in various types of cartridge. The surface treatment is the same as aluminum plate.
7. Stainless steel; Mainly used for no surface treatment, high cost.
