For the sheet metal stamping forming its material, including SECC (electric galvanized steel), SGCC (hot 濅 electric galvanized steel) (SPCC) (cold plate), SUS (stainless steel), aluminum, copper, etc.
1.SPCC (cold rolled steel plate) :
Cold rolled steel is hot rolled steel coil after pickling, rolled to 0.30-3.20mm in cold rolling workshop at normal temperature, through electrolytic cleaning, annealing and conditioning process. Cold-rolled steel products because of thin thickness, accurate size, surface roughness classification, easy painting and electroplating, and mechanical properties and good machinability, easy sheet metal into a variety of products, so very wide use, such as automobile body, electronic parts, household appliances, steel furniture, containers, a large number of cold-rolled steel products as processing materials.
SPCC: easy to scratch, oxidation, rust, during the production process to wear gloves, spray on anti-rust oil, each piece of product with bubble bag layer by layer separated, generally do surface plating treatment; Do not touch it directly with hands or dirty gloves after electroplating to prevent fingerprints or dirt on it.
2.SECC(electric galvanized steel plate) :
The bottom material of electrogalvanized steel coil is general cold-rolled steel coil. After the process of degreasing, pickling, electroplating and various post-treatment in the continuous electrogalvanized production line, it becomes electrogalvanized products. The characteristics of this product not only have the mechanical properties of general cold-rolled steel sheet and similar machinability, but also have excellent corrosion resistance and decorative appearance; In the market of electronic products, home appliances and furniture has a great competitiveness and substitution
SECC, widely used in communications, PC products, electronic products; Because the surface is easy to scratch, in the case of no paint need to pay special attention to the surface can not scratch;
SECC is divided into Baosteel, Sinosteel, South Korean material, Japanese material and Taiwan material, whose surface color is different, so it is necessary to pay attention to the color difference when assembling multiple material numbers;
3. SPTE(tin) :
Is a kind of ultra-thin cold rolled low carbon steel sheet, the main purpose is to supply tin plating, chromium plating iron skin used in the can industry. Strong electrical conductivity, good appearance, due to cost considerations to replace SUS, non-magnetic material, but the more stamping processing times, the stronger the magnetic.
4. PHOSPHOR BRONZE SPRING (PBS)PHOSPHOR BRONZE SPRING:
Phosphor bronze is composed of bronze (copper-tin alloy) with deoxidizing agent, phosphorus (P) content 0.03 ~ 0.35% and other trace elements such as Fe, Zn, etc. Excellent ductility and fatigue resistance, can be used for electrical and mechanical materials, and corrosion resistance, material reliability is higher than the general copper alloy products, made of continuous melting casting (sheet, copper coil), with a high degree of material uniformity. Good electrical conductivity, high elasticity, rich wear resistance; It is a shrapnel and conductive material for electrical switch, terminal and other applications, but not as strong as stainless steel. Appearance shall be electroplated.
5. BERYLLIUM Copper (BECU) BERYLLIUM CU:
High conductivity, high elasticity, is the best hardness and strength of all copper alloys; Most suitable for high temperature, high current switch parts, age hardening material. Micro switch, a variety of advanced terminals, relays and other precision shrapnel materials. The properties are similar to PBS, but after heat treatment, better hardness and elasticity can be obtained. The appearance needs electroplating, but the cost is high.
6. SUS304(Stainless) :
The most used stainless steel, because containing Ni is richer than Cr steel corrosion resistance heat resistance, and has low temperature strength, so the mechanical characteristics are very good, work hardening is very large, heating treatment is not hardening, non-magnetic, good strength, no elasticity, often used between 0.4T ~ 1.0T thickness. So Notebook is often widely used in Bracket which needs structural strength.
8. SUS301(Stainless Steel) :
Cr (chromium) composition is lower than SUS304, corrosion resistance is poor, but cold processing can get a very high degree of tensile and hardness, its characteristics and uses, because of good elasticity, but commonly used thickness between 0.4T ~ 0.07T. Use must be specified in order to achieve the design requirements (e.g. elasticity, strength).
