sheet metal stamping has following material:
According to NOBLE machining manufacturers statistics, suitable for stamping process sheet metal material is very large, widely used in the electrical and electronic industry, sheet metal materials including:
⒈ common cold-rolled plate SPCC: SPCC refers to the continuous rolling of the ingot through the cold rolling mill into the required thickness of the coil material or sheet. SPCC surface without any protection, exposed to the air can be easily oxidized, especially in humid environments accelerated oxidation, the emergence of dark red rust, the use of the surface to paint, plating or other protection.
⒉ galvanized steel SECC: SECC substrate for the general cold-rolled coil, galvanized steel in the continuous after degreasing, pickling, plating and various post-processing process, that is, become galvanized products. SECC not only has the general cold-rolled steel mechanical properties and approximate processibility, but also has excellent corrosion resistance and decorative appearance. In the electronics, home appliances and furniture market has great competition and substitutability. For example, the computer chassis is commonly used SECC.
⒊ Hot-dip galvanized steel plate SGCC: Hot-dip galvanized steel coil refers to the hot-rolled pickling or cold-rolled semi-finished products, after cleaning, annealing, immersed in a molten zinc bath temperature of about 460 ° C, On the zinc layer, then quenched and leveled and chemical treatment made. The SGCC material is harder than the SECC material with poor ductility (avoiding deep draw design), a thicker zinc coating and poor weldability.
⒋ Stainless steel SUS301: Cr (chromium) content lower than SUS304, corrosion resistance is poor, but after cold work can get good tensile strength and hardness, good elasticity, and more for the shrapnel springs and EMI.
⒌ Stainless steel SUS304: One of the most widely used stainless steels, due to Ni-containing steels is more corrosion-resistant and heat-resistant than Cr-containing steels, has very good mechanical properties, no heat treatment and hardening, elasticity.
