The code description of the commonly used raw materials for precision stamping parts 'Hardware'

Description of the codes of commonly used raw materials for precision stamping parts: SPCC: (Cold-rolled carbon steel sheet) This material can be divided into two types: single light and double light. This material is very easy to scratch and rust. Wear gloves when transporting. If it is stored or unloaded for a long time, it must be coated with anti-rust oil to prevent rust and scratches on the material. SECC: (Electrolytic lead zinc-plated steel sheet) Because there are many sources of this material, it is roughly divided into: 1. Taiwan (China Steel) 2. Japan (NKK, Nippon Steel, Kobe) 3. Made in Korea, because there are more types, We need to pay attention when choosing materials. It is resistant to fingerprints, has excellent corrosion resistance, and adheres to the workability of cold-rolled sheets. SGCC: (Hot-dip galvanized steel sheet) The Taiwan material number is GI material, and the appearance is divided into two types: pattern and no pattern. SPHC: (Hot-rolled steel plate) is generally called hot-rolled plate or black iron plate. This material has high hardness and is mainly used for the manufacture of simple process molds. SPTE: (tin plate, commonly known as tinplate) This material is easy to rust and scratch. SGLD: (Aluminum-plated zinc steel sheet) is a multi-phase alloy material including aluminum-rich and zinc-rich. Due to the characteristics of aluminum and zinc, it has better performance than SGCC. SK: (Carbon tool steel) There are three commonly used SK materials: SK-3, SK-5, and SK-7. AL: (Aluminum) is easily scratched and crushed. Common models are 1050 and 5020. This kind of material has textures and is easy to break when bent. CU: (Copper) There are bronze, phosphor bronze, brass, and copper (difficult to cut by laser). SUS: There are 301, 302, 304, 430, etc. on the market. 301 has good elasticity, is harder, non-magnetic, and has lines. Generally, it is necessary to rotate 45 degrees during cutting to avoid breaking when bending. 304 has poor elasticity, softness, non-magnetism, and no lines. 430 is magnetic.
