The Main Uses Of Sheet Metal

There are many sheet metal materials suitable for stamping processing, and sheet metal materials widely used in the electronic and electrical industry include:
Ordinary cold rolled plate SPCCSPCC refers to the steel ingot through the cold rolling machine continuous rolling into the required thickness of the steel sheet coil or sheet. SPCC surface does not have any protection, exposed to the air is very easy to be oxidized, especially in a humid environment, oxidation speed is accelerated, dark red rust, the surface should be painted, electroplated or other protection when in use.
The base material of galvanized steel plate SECCSECC is a general cold-rolled steel coil, which becomes an electrogalvanized product after degreasing, pickling, electroplating and various post-treatment processes in the continuous electrogalvanizing production line. SECC not only has the mechanical properties of general cold-rolled steel sheet and similar machinability, but also has superior corrosion resistance and decorative appearance. It has great competitiveness and substitution in the market of electronic products, home appliances and furniture. For example, SECC is commonly used in computer cases.
Hot dip galvanized steel SGCC Hot dip galvanized steel coil refers to the semi-finished product after hot pickling or cold rolling, after cleaning, annealing, immersed in a melting zinc tank at a temperature of about 460°C, and the steel sheet is plated with zinc layer, and then by conditioning and leveling and chemical treatment. SGCC material is harder than SECC material, poor ductility (avoid deep drawing design), thicker zinc layer, poor weldability.
Stainless steel SUS301Cr (chromium) content is lower than SUS304, corrosion resistance is poor, but after cold processing can obtain good tension and hardness, good elasticity, more used for shrapnel springs and EMI.
Stainless steel SUS304 one of the most widely used stainless steel, because containing Ni (nickel) than containing Cr (chromium) steel richer corrosion resistance, heat resistance, with very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.
