Sheet metal case

Mechanical sheet metal processing generally used materials are cold-rolled plate, hot-rolled plate, galvanized sheet, brass, copper, beryllium copper, aluminum plate, stainless steel, according to the different role of the product, the selection of different materials, generally need to be considered from the use of the product and cost.

1, cold-rolled plate SPCC, mainly with electroplating and paint parts, low cost, easy to form, material thickness ≤3.2mm.

2, hot rolled plate SHCC, material T≥3.0mm, also with electroplating, paint parts, low cost, but difficult to form, mainly with flat parts.

3. Galvanized sheet SECC, SGCC. SECC electrolytic plate is divided into N material and P material, N material is mainly not surface treatment, the cost is high, and P material is used for spraying parts.

4. Copper; Mainly used conductive materials, its surface treatment is nickel plating, chromium plating, or no treatment, high cost.

5, aluminum plate; General use of surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.

6, aluminum profile; Materials with complex sectional structure are widely used in various plug-in boxes. The surface treatment is the same as aluminum plate.

7, stainless steel; It is mainly used without any surface treatment, and the cost is high.
