Choosing the right alloy for each purpose

Aluminium is light, strong, corrosion resistant, recyclable, durable and tough and it conducts heat and electricity very efficiently. These characteristics make it an ideal material for countless different purposes. In the manufacturing of aluminium profiles, we make use of its excellent formability. Choosing the right alloy is important because it affects many of the aluminium’s characteristics: formability, tensile properties, surface treatment options, machinability and electric conductivity.

Choosing the ideal alloy for each purpose is a critically important step in profile manufacturing. The professional skills of our sales department and profile designers are at your service.

Purity and even alloy quality are important when aiming to produce high-quality, dimensionally accurate aluminium profiles.   That is why we only use billets smelted from primary aluminium in the Nordic countries when manufacturing our profiles. Nordic billets are the purest in the world, thanks to the methods used to produce them.

The waste produced in the process is collected and re-used as profile material in our own foundry: this way we can ensure the purity of our materials in every phase. The mechanical and chemical properties of the profiles we make are defined by the EN 573-3 and EN 755-2 standards.
