Aluminum extrusion is a process in which the raw material aluminum can be formed into targeted shape. The aluminum bar is usually heated via pot arch to 480℃. The heated aluminum bar then will be extrusion forming in the mould.
The extrusion strength of aluminum profiles can meet the needs of most applications. Due to the nature of the extrusion process, the strength can be concentrated where it is really needed. The profile design includes different wall thicknesses and internal reinforcements.
Aluminum profile has excellent corrosion resistance. They will not rust, and the surface of the aluminum is protected by its own natural oxidation file. This protection can be enhanced by anodizing or other finishing processes.
Surface treatment can produce high reflectivity on aluminum components, making aluminum extrusion attractive for lighting applications, or in areas that need to be shielded from light, radio waves, or infrared radiation.
The weight of aluminum is about 1/3 that of iron, steel, copper or brass, which makes aluminum extrusions easier to handle and lower transportation costs. Aluminum is an attractive material in applications where weight reduction is prioritized, such as transportation and other moving parts.
In pounds, aluminum is twice as conductive as copper, which makes extrusion a cost-effective alternative to electrical connectors and bus bar distribution components.
