The materials commonly used in Shenzhen sheet metal processing plants are cold rolled sheet (SPCC), hot rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum sheet (6011). 5052, 1010, 1060, 6063, hard aluminum, etc.), aluminum profiles, stainless steel (mirror, brushed surface, matte surface), depending on the product's role, different materials, Shenzhen sheet metal processing plant generally needs to come from the product's use and cost consider.
1, cold-rolled plate SPCC, mainly used for electroplating and baking parts, low cost, easy to form, material thickness ≤ 3.2mm.
2, hot-rolled plate SHCC, material T ≥ 3.0mm, also used electroplating, painted parts, low cost, but difficult to form, mainly using flat pieces.
3, galvanized sheet SECC, SGCC. SECC electrolytic board is divided into N material and P material. N material is mainly used for surface treatment, and the cost is high. P material is used for spraying parts.
4. Copper; mainly used for conductive materials, the surface treatment is nickel plating, chrome plating, or no treatment, and the cost is high.
5. Aluminum plate; generally used surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6, aluminum profiles; materials with complex cross-section structure, used in a variety of plug-in boxes. The surface treatment is the same as the aluminum plate.
7, stainless steel; mainly used without any surface treatment, high cost.
