Sheet metal material:
1, cold-rolled plate SPCC, the main plating and paint parts, low cost, easy molding, material thickness ≤ 3.2mm.
2, aluminum profiles; cross-section structure of the complex parts, a large number of used in a variety of subracks. Surface treatment with aluminum.
3, copper; the main role of conductive materials, the surface treatment is nickel, chrome, or not for processing, high cost.
4, hot-rolled plate SHCC, material T ≥ 3.0mm, is also electroplating, paint pieces, low cost, but difficult to shape, the main flat parts.
5, aluminum; general use of surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver-plated, nickel-plated.
6, galvanized steel SECC, SGCC. SECC electrolytic plate sub-N material, P material, N material mainly without surface treatment, high cost, P material for spraying parts.
7, stainless steel; mainly without any surface treatment, high cost.
