There  are many sheet metal materials suitable for stamping processing. Sheet  metal materials widely used in the electrical and electronic industry  include:

1. Ordinary cold rolled sheet SPCC

SPCC  refers to the continuous rolling of steel ingots into coils or flakes  of the required thickness through cold rolling mills. The surface of  SPCC does not have any protection. It is easily oxidized when exposed to  air, especially in humid environments. Dark red rust, painted, plated or otherwise protected during use.

2. Galvanized steel sheet SECC

SECC's  substrate is a general cold-rolled steel coil, which becomes an  electro-galvanized product after the continuous electro-galvanizing line  has been degreased, pickled, electroplated and various post-treatment  processes. 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, SECC is commonly used in computer cases.

3. Hot dip galvanized steel sheet SGCC

Hot-dip  galvanized steel coil refers to the semi-finished product after  pickling or cold rolling, which is washed, annealed, immersed in a  molten zinc bath at a temperature of about 460 ° C, and the steel sheet  is plated with zinc layer and then tempered. Leveling and chemical treatment. SGCC  materials are harder and less ductile than SECC materials (avoiding  deep draw design), thicker zinc layers, and poor weldability.

4, stainless steel SUS301

The  content of Cr (chromium) is lower than that of SUS304, and the  corrosion resistance is poor. However, after cold working, it can obtain  good tensile strength and hardness, and has good elasticity. It is  mostly used for springs and EMI.

5, stainless steel SUS304

One  of the most widely used stainless steels, because it contains Ni  (nickel), is more resistant to corrosion and heat than steel containing  Cr (chromium). It has very good mechanical properties, no heat treatment  and hardening, and no elasticity.
