Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including cutting, punching/cutting/composite, folding, welding, riveting, splicing, forming, etc. Its prominent feature is that the thickness of the same component is consistent. The products processed through sheet metal technology are called sheet metal parts. There are many sheet metal materials suitable for stamping processing, and the sheet metal materials widely used in the electronic and electrical industry include: 1. Ordinary cold-rolled sheet SPCC SPCC refers to the continuous rolling of steel ingots into steel coils or sheets of the required thickness by a cold rolling mill. The surface of SPCC has no protection and is highly susceptible to oxidation when exposed to air, especially in humid environments where the oxidation rate accelerates and dark red rust appears. When in use, the surface should be painted, electroplated, or otherwise protected. 2. Galvanized steel plate SECC The substrate of SECC is a general cold-rolled steel coil, which becomes an electroplated product after undergoing degreasing, acid washing, electroplating, and various post-treatment processes in a continuous electroplating production line. 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. 3. Hot dip galvanized steel plate SGCC Hot dip galvanized steel coil refers to a semi-finished product that has been hot-rolled, pickled, or cold-rolled, cleaned, annealed, and immersed in a molten zinc bath at a temperature of about 460 ° C to coat the steel sheet with a zinc layer, and then quenched, tempered, leveled, and chemically treated. 4. Stainless steel SUS301 The content of Cr (chromium) is lower than that of SUS304, and its corrosion resistance is poor. However, after cold processing, it can obtain good tensile strength and hardness, and has good elasticity. It is mostly used for spring plates and EMI prevention. 5. Stainless steel SUS304 One of the most widely used stainless steels, it has better corrosion resistance and heat resistance than steel containing Cr (chromium) due to its Ni (nickel) content. It has excellent mechanical properties, no heat treatment hardening phenomenon, and no elasticity.
