Suitable for stamping processing of sheet metal materials are very large, widely used in the electrical and electronic industry, sheet metal materials include:
⒈ ordinary cold-rolled plate SPCC SPCC refers to the ingot through the cold rolling mill continuous rolling into the required thickness of the coil material or sheet material. SPCC surface without any protection, exposure to the air can easily be oxidized, especially in humid environment, the speed of oxidation, dark red rust, the use of the surface to paint, plating or other protection.
⒉ galvanized steel plate SECC SECC substrate for the general cold-rolled coil, continuous electro-galvanized production line through the degreasing, pickling, electroplating and a variety of post-processing process, that is, galvanized products. SECC not only has the general cold-rolled steel sheet mechanical properties and approximate processing, but also has excellent corrosion resistance and decorative appearance. In the electronic products, home appliances and furniture on the market has a great competitive and replace the. For example, the computer chassis is commonly used is SECC.
⒊ hot-dip galvanized steel plate SGCC hot-dip galvanized steel coil is hot-rolled pickling or cold-rolled after the semi-finished products, after cleaning, annealing, immersed in the temperature of about 460 ° C melting molten zinc tank, Zinc layer, and then by the conditioning and leveling and chemical treatment. SGCC material than the SECC material hard, poor ductility (to avoid deep pumping design), zinc layer thick, poor welding.
⒋ stainless steel SUS301 Cr (chromium) content than SUS304 low corrosion resistance is poor, but after cold processing can get a good tension and hardness, flexibility is better, more for shrapnel spring and anti-EMI.
⒌ stainless steel SUS304 one of the most widely used stainless steel, because Ni (nickel) than Cr (chromium) than the steel is more rich corrosion resistance, heat resistance, has a very good mechanical properties, no heat treatment hardening.
