Suitable for stamping sheet metal material very much, is widely used in electrical and electronic industry, sheet metal materials include:
1. Ordinary SPCC cold rolled sheet
SPCC cold rolled steel ingot means continuous rolling machine into the desired thickness of the steel sheet roll or sheet material. SPCC surface without any protection, exposure to easily oxidized in air, oxidation speed, especially in humid environments, appear dark red rust, in the use of the surface to be painted, plated or other protection.
2. galvanized steel SECC
SECC substrates for the average cold rolled coil, galvanized in a continuous production line after degreasing, pickling, electroplating and various post-treatment process, it becomes galvanized products. SECC not only has the mechanical properties of cold-rolled steel sheet and approximate general workability, and has excellent corrosion resistance and decorative appearance. Has a great competitive and substituting in the electronic products, home appliances and furniture market. For example, the widespread use of computer chassis is SECC.
3. Hot-dip galvanized steel SGCC
Hot-dip galvanized steel coil refers to semi-finished products after the hot pickling or cold, after cleaning, annealing temperature of about 460 ° C immersed in molten zinc bath, leaving the steel coated with zinc layer, and then by quenching leveling and chemical treatment from. SGCC material harder than the material SECC, ductility (avoid deep drawing design), zinc layer is thicker, poor welding.
4. Stainless steel SUS301
(Cr) content of Cr lower than the SUS304, corrosion resistance is poor, but after cold working can get a good tension and hardness, good elasticity, and more for shrapnel springs and anti-EMI.
5. Stainless steel SUS304
One of the most widely used stainless steel, because it contains Ni (nickel) so than containing Cr (chromium) steel richer corrosion resistance, heat resistance, have very good mechanical properties, non-hardening heat treatment, there is no flexibility.
