Aluminum profile is a product with a certain cross-section shape and dimensional accuracy made of aluminum alloy material through extrusion or rolling and other processes. It has the advantages of light weight, corrosion resistance, good electrical conductivity, easy processing, etc., so it is widely used in construction, transportation, electrical and electronic, mechanical equipment and other fields. In this article, we will introduce the basics of aluminum profiles:
Ⅰ Classification of aluminum profiles
Aluminum profiles are mainly classified according to the cross-section shape, and the common ones are square tube, round tube, angle material, T profile, etc.
Among them, flat profiles are suitable for various processing techniques, such as cutting, stamping, welding, etc.; square tube profiles are suitable for the manufacture of structural parts and components such as gratings; round tube profiles are suitable for the production of containers, pipes, etc.; angle profiles are suitable for the production of frames and structural parts; T profiles are suitable for the production of panels and shelves.
Ⅱ Selection of aluminum alloy
The material of aluminum profile is generally aluminum alloy, and different alloy compositions have different influences on the mechanical properties, corrosion resistance, processability and so on.
According to the specific use requirements, the commonly used aluminum alloy can be choosed as follows: 1xxx series, with good weldability and corrosion resistance; 2xxx series, with good strength, but poor weldability; 3xxx series, with good machinability and corrosion resistance; 5xxx series, with good corrosion resistance and weldability, suitable for marine environments and other corrosive occasions; 6xxx series, with good machinability and corrosion resistance; 6xxx series, with good machinability and corrosion resistance; 6xxx series. With good workability and corrosion resistance; 7xxx series, with high strength.
Ⅲ Aluminum profile features
1. Light weight: the density of aluminum is only 2.7g/cm³, compared with steel, the weight of aluminum is only 1/3, which is easy for transportation and installation.
2. Good corrosion resistance: Aluminum has a self-contained oxide film that can resist corrosion by atmosphere, water and some common chemicals.
3. Good conductivity: Aluminum is a good conductive material with low electrical resistance and low magnetoresistance, suitable for electrical and electronic fields.
4. Good workability: Aluminum has good plasticity and workability, and can be processed into various shapes and sizes through extrusion, rolling, stretching, pressure forming and other processes.
5. Good environmental protection: Aluminum can be recycled, in line with the concept of sustainable development.
