Sheet Metal Processing material

material
The choice of materials, sheet metal, and commonly used materials are cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum ( 6061, 6063, hard aluminum, etc.), Aluminum profiles, stainless steel (mirror, brushed surface, matte surface), depending on the role of different products, the choice of materials is different, generally need to consider the use of the product and cost.
1. Cold-rolled plate SPCC: mainly used for electroplating and baking paint parts, low cost, easy molding, material thickness ≤ 3.2mm.
2. Hot-rolled plate SHCC: material T ≥ 3.0mm, is also used for electroplating, paint pieces, low cost, but difficult to form, mainly used flat pieces.
3. Zinc plate SECC, SGCC: SECC 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: The main use of conductive materials, the surface treatment is nickel, chrome, or no treatment, high cost.
5. Aluminum: General use of surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6. Aluminium profiles: Material parts with a complex cross-section structure are used extensively in various plug boxes. Surface treatment with aluminum plate.
7. Stainless steel: Mainly used without any surface treatment products, high cost.
