Aluminum alloys

About the material

Aluminium alloys combine low weight with high functionality – with a density of around 2.7 g/cm³, aluminium weighs only around a third as much as steel. At the same time, it offers excellent corrosion resistance, good malleability and very high thermal conductivity. These properties make aluminium one of the most important light metal materials in modern industrial applications – from automotive technology to aerospace and electronic precision parts.

A natural oxide layer (Al₂O₃) reliably protects the surface against environmental influences and ensures an appealing look. Added to this is its outstanding recyclability: aluminium can be almost entirely recycled while maintaining the same quality.

Studer-Biennaform processes aluminium alloys into cold-rolled precision flat wire. This is particularly suitable for applications in which weight savings, high formability and excellent surface quality are required – for example, in precision mechanics, electrical engineering and lightweight construction.

AlMg3 (EN AW-5754 / 3.3535 / AA5754)

The alloy EN AW-5754, also known as AlMg3, belongs to the group of non-curable, medium-strength aluminium-magnesium alloys with a magnesium content of around 3.1%. It combines good mechanical strength with excellent corrosion resistance – especially against seawater and industrial atmospheres. At the same time, it offers excellent formability and weldability, which qualifies it for a variety of technical and decorative applications.

In the soft-annealed state (e.g. O or H111), EN AW-5754 has excellent cold-forming properties – for example, by deep drawing, pressing or bending complex geometries. The mechanical strength can be significantly increased by work hardening (e.g. H32, H34) without significantly impairing the ductility. The alloy is also particularly easy to weld, for example, using MIG or TIG welding with AlMg5 additive. The surface can be anodised, which opens up additional possibilities for decorative corrosion protection.

Typical applications can be found in automotive engineering (e.g. body panels, chassis parts), shipbuilding (bulkheads, decks, superstructures resistant to salt water) as well as in electrical engineering and precision mechanics – for example for cases, covers or decorative components in the watchmaking and jewellery industries.

In the form of cold-rolled precision flat wire, EN AW-5754 is particularly suitable for lightweight structural components, clips, clamps or resistant elements where low weight, tight dimensional accuracy and reproducible quality are required.
