There are many sheet metal materials suitable for the fabrication of automotive sheet metal parts, but the sheet metal materials commonly used in the electronic and electrical industry only include the following categories:
1. Ordinary cold rolled sheet SPCC
SPCC refers to the continuous rolling of steel ingots into steel coils or sheets of required thickness through a cold rolling mill. The surface of SPCC has no protection, and is easily oxidized when exposed to the air, especially in a humid environment, the oxidation speed is accelerated, showing dark red rust, and the surface should be painted, electroplated or otherwise protected during use.
2. Galvanized steel sheet SECC
The substrate of SECC is ordinary cold-rolled steel coil, which becomes an electro-galvanized product after degreasing, pickling, electroplating and various post-fabrication processes in a continuous electro-galvanizing production line. SECC not only has the mechanical properties and similar workability of ordinary cold-rolled steel sheets, but also has superior corrosion resistance and decorative appearance. It has great competition and substitution in the market of electronic products, home appliances and furniture. For example, the commonly used computer case is SECC.
3. Hot dip galvanized steel sheet SGCC
Hot-dip galvanized steel coil refers to the semi-waste products after hot-rolling pickling or cold-rolling, after cleaning, annealing, and immersing in a molten zinc bath with a temperature of about 460 ° C, so that the steel sheet is plated with a zinc layer, and then adjusted. Quality levelling and chemical treatment. SGCC material is harder than SECC material, has poor ductility (prevents deep drawing design), thicker zinc layer and poor weldability.
4. Stainless steel SUS301
The content of Cr (chromium) is lower than that of SUS304, and the corrosion resistance is poor, but it can obtain good tensile force and hardness after cold working, and has good elasticity. It is mostly used for shrapnel springs and anti-EMI.
5. Stainless steel SUS304
One of the commonly used stainless steels, because it contains Ni (nickel), it is richer in corrosion resistance and heat resistance than steel containing Cr (chromium), has very good mechanical properties, has no heat treatment hardening phenomenon, and has no elasticity.
