Suitable for stamping processing of sheet metal materials is very large, widely used in the electrical and electronic industry, sheet metal materials include:
⒈ ordinary cold-rolled plate SPCC SPCC refers to the steel ingot through the cold rolling mill continuous rolling into the required thickness of the coil or sheet material.SPCC surface without any protection, exposure to the air can easily be oxidized, especially in humid environments In the oxidation speed, dark red rust, in the use of the surface to paint, plating or other protection.
⒉ galvanized steel plate SECC SECC substrate for the general cold-rolled coil, in the continuous galvanized production line through degreasing, pickling, electroplating and a variety of post-processing process, it becomes galvanized products.SECC not only has a general cold rolling Steel sheet mechanical properties and approximate processing, but also has excellent corrosion resistance and decorative appearance. In the electronic products, home appliances and furniture 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 molten zinc tank, and the use of steel plated 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) low content SUS304 low corrosion resistance is poor, but after cold processing can get a good tension and hardness, flexibility is better, more for shrapnel and anti-EMI.
⒌ stainless steel SUS304 one of the most widely used stainless steel, due to 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.
