Suitable for stamping sheet metal material is very much, widely used in the electronic and electrical industry sheet metal materials include:
⒈ Ordinary Cold Rolled Plate SPCCSPCC refers to the ingot through the cold rolling mill continuously rolled into the required thickness of the steel plate coils or sheets.SPCC surface without any protection, exposed to the air is very susceptible to oxidation, especially in the humid environment oxidation rate Accelerate the speed of oxidation, the appearance of dark red rust, in the use of the surface to be painted, plated or other protection.
PIECE Galvanized steel SECC SECC substrate for the general cold rolled steel coils, in the continuous zinc plating production line after degreasing, pickling, plating and a variety of post-processing processes, that is, become an electro-galvanized products. SECC not only has the mechanical properties of the general cold rolled steel sheet and similar processability, but also has a superior corrosion resistance and decorative appearance. In the market of electronic products, home appliances and furniture, SECC has great competitiveness and substitutability. For example, computer chassis are commonly used is SECC.
3 Hot dip galvanized steel SGCC hot dip galvanized steel coils refers to the hot rolled pickled or cold rolled semi-finished products, after cleaning, annealing, immersed in the temperature of about 460 ° C in the molten zinc tank, and so that the steel coils plated with zinc, and then by the tempering of the leveling and chemical treatment and become. SGCC material is more than the SECC materials, hard, ductility is poor (to avoid the deep pumping), thicker zinc layer, and the material is more than the SGCC material, hard, ductility (avoid deep pumping). SGCC material is harder than SECC material, less ductile (to avoid deep drawing), thicker zinc layer, and less weldable.
Sung stainless steel SUS301Cr (chromium) content is lower than SUS304, corrosion resistance is poor, but after cold working can get very good tensile strength and hardness, elasticity is better, more used in shrapnel springs and anti-EMI.
Be careful with the stainless steel SUS304 is one of the most widely used stainless steel, due to the content of Ni (nickel), so it is richer than the steel containing Cr (chromium) corrosion resistance, Heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.
