The Sheet metal processing is often used in our life a way of processing.First of all, let us know, sheet metal process for the material selection?

   一、 Material selection:

       Sheet metal and commonly used materials are cold rolled sheet (SPCC),Hot rolled plate (SHCC), galvanized plate (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum plate (6061, 6063, hard aluminum, etc.), aluminum profile, stainless steel (mirror, wire drawing surface, fog surface), It depends on the product. Choose material to differ, need to come up from its use and cost to consider from the product commonly.

 1. Cold rolled sheet SPCC.

        Mainly with electroplating and baking lacquer.

        Low cost, easy to shape, material thickness 3.2mm.

2. Hot rolled plate SHCC.

        Material T 3.0mm, also by electroplating, paint, low cost, but difficult to shape, mainly with flat pieces.

3. Galvanized sheet SECC, SGCC.SECC electrolytic plate is divided into N materials and P materials.

        N material is not mainly for surface treatment.

        High cost, P material for spray parts.

4. Copper：

        Mainly used for conductive materials, the surface treatment is nickel plating, chrome plating, or not for treatment, high cost.

5. Aluminum plate：

        Surface chromate (j11-a), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.

6.Aluminum profile:

        Materials with complex section structure are widely used in various boxes. The surface treatment is the same as aluminum plate.

7. Stainless steel：

         The main use does not make any surface treatment, high cost.
