There are many sheet metal materials suitable for stamping. Sheet metal materials widely used in the electronics industry include:

Common cold rolled plate SPCC

SPCC refers to the continuous rolling of steel ingots into cold rolled steel sheets or sheets of required thickness. There is no protection on the surface of SPCC. It is very easy to be oxidized when exposed to the air, especially in a humid environment. The oxidation speed is accelerated, and dark red rust appears. The surface should be painted, electroplated or other protection during use.

2. Galvanized steel sheet SECC

The substrate of SECC is general cold-rolled steel coil. After continuous degreasing, pickling, electroplating and various post-treatment processes, it becomes an electro-galvanized product. SECC not only has the mechanical properties and approximate processability of general cold rolled steel sheets, but also has superior corrosion resistance and decorative appearance. It has great competitiveness and substitution in the market of electronic products, home appliances and furniture. For example, the computer case is commonly used in SECC.
