All about Aluminum profiles

Aluminum profiles are usually  standardized  or  purpose-specific semi –  finished products  and are always used where low weight and high stability are required. Like most semi-finished products, however, they are not made of pure aluminum, but are made from hardenable or naturally hard  aluminum alloys

Due to the excellent formability of the light metal, the aluminium extrusion singapore process is usually used in production, in which an aluminum billet, preheated to around 450 ° C to 500 ° C, is pressed through an opening in a die at high pressure. This in turn has the desired cross-section of the later aluminum profiles, so that they have exactly the desired geometric shapes after extrusion.

Which aluminum profiles are there?

Aluminum profiles  are available in a wide variety of designs, for example:






Store Profile


Special profiles

In the case of the latter two aluminum profile variants, in addition to the die, mandrels  are also used in order  to form the customer-specific or application-specific  cavities in the aluminum profiles  . Since the aluminum profiles deform when they cool down, they then have to be “stretched” – that is, stretched in order to release all tension and achieve the desired straightness.

The aluminum profiles are later sawn to the desired length. The duration of the cooling process can be between four and ten hours, depending on the aluminum alloy used or the required mechanical properties. The aluminum profiles are then ready for further processing or surface treatment.
