- What are the common sheet metal processing materials?
1. Cold rolled sheet
It is further cold-rolled from ordinary carbon structural steel hot-rolled steel sheets with a thickness of less than 4mm. Because it is rolled at room temperature, no oxide scale is produced, so the surface quality is good, the dimensional accuracy is high, and it has good mechanical and technological properties after annealing. It is a commonly used metal material for sheet metal processing. Among them, the delivery in sheets is called steel plate, also known as box plate or flat plate; the delivery in coils with relatively long length is called steel strip, also known as coil plate.
- Stainless steel
Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. In practice, steel that is resistant to weak corrosive media is often called stainless steel, and steel that is resistant to chemical media is called acid-resistant steel. At present, the market of stainless steel is very large, and the application range is also relatively wide.
3. Aluminum plate
Aluminum is a light metal junction material with good corrosion resistance, electrical and thermal conductivity. Under the same weight, the conductivity of aluminum is 2 times higher than that of copper, and the strength of pure aluminum is very low, so it cannot be used as a structural material. Generally, aluminum alloy plates are used for sheet metal processing.
4. Copper plate
Commonly used are copper, brass, bronze and beryllium copper. The appearance of red copper is purple, and it has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. However, it is more expensive. It is mainly used as a conductive and thermally conductive material, and is generally used in power supplies that need to carry large currents. Due to its low strength, copper cannot be used as a structural member.
Brass has good ductility and punchability, and has good resistance to seawater and atmospheric corrosion when used for electroplating.
Bronze has better wear resistance than pure copper and brass: good machinability and corrosion resistance. Beryllium copper refers to a copper alloy containing beryllium (Be), which is mostly used as an electromagnetic shielding material.
5. Hot dip galvanized steel sheet
Electroplating or hot-dip galvanizing steel plate with a layer of about 5-12 microns metal zinc, which can prevent corrosion and is widely used in construction, home appliances, automobiles, etc. At present, the performance of hot-dip galvanized steel sheet is very good. First, it has excellent corrosion resistance, paintability, decorative properties and good formability.
The above materials are common materials in sheet metal processing at present. With the continuous improvement of sheet metal processing technology, more and more types of materials will be processed.
