The main purpose of sheet metal
- Jan 23, 2018 -

Suitable for stamping process sheet metal material is very large, widely used in electrical and electronic industry sheet metal materials include:

⒈ ordinary cold-rolled plate SPCC SPCC refers to the continuous rolling of the ingot through the cold rolling mill into the required thickness of the coil material or sheet. SPCC surface without any protection, exposed to the air can easily be oxidized, especially in humid environment, accelerated oxidation, the emergence of dark red rust, when used to paint the surface, electroplating or other protection.

⒉ galvanized steel SECC SECC substrate for the general cold-rolled coil in the continuous galvanized line after degreasing, pickling, electroplating and a variety of post-processing process, which became electrogalvanized products. SECC not only has the general cold-rolled steel mechanical properties and approximate processibility, but also has excellent corrosion resistance and decorative appearance. In the electronics, home appliances and furniture market has great competition and substitutability. For example, the computer chassis is commonly used SECC.

⒊ Hot dip galvanized steel plate SGCC hot dip galvanized steel coil refers to the hot-rolled pickling or cold-rolled semi-finished products, after cleaning, annealing, immersed in a molten zinc bath temperature of about 460 ° C, and the steel plate Zinc layer, then quenched and leveled and chemical treatment made. The SGCC material is harder than the SECC material with poor ductility (avoiding deep draw design), a thicker zinc coating and poor weldability.
