The high ductility of aluminium means that the metal can be easily moulded into a variety of sections without expending a lot of energy in processing or forming, and the melting point of aluminium is usually about half that of ordinary steel. Both of these facts mean that the energy consumption of the extruded aluminium profile
process is relatively low, resulting in lower die and manufacturing costs. Finally, aluminum also has a high strength-to-weight ratio, making it a good choice for industrial applications.
A variety of complex extruded aluminum profiles can be created in different thicknesses. To facilitate a variety of automated applications and to meet any performance weight requirements, a variety of internal voids can be used.
2. Surface type
As a by-product of the extrusion process, the profiles sometimes appear as fine, almost invisible lines on the surface. This is the result of the formation of auxiliary tools during extrusion, and other surface treatments can be specified to remove these lines. To improve the surface finish of the section of the profile, some minor surface treatment operations can be performed, such as face milling after the main extrusion molding process. These machining operations can be specified to improve the geometry of the surface by reducing the overall surface roughness of the extrusion profile to improve the part profile. These treatments are usually specified in applications where precise positioning of parts is required or where tight control of the fitting surface is necessary.
Aluminum profiles are most commonly used in industrial automation applications, such as assembly lines and automated motion applications throughout the manufacturing industry. They are strong and lightweight, so they can be easily handled manually and can be built in various configurations as required by automated structures. Structural grade aluminum profiles are even designated as part of the weight reduction beyond traditional automation applications. In this sense, they are increasingly being used as a framework for other end-use consumer goods. With the development of more advanced aluminum alloys and surface coating technology, its use is expanding into these new areas.
