Aluminiumvariante

Aluminiumvariante is a term used in materials engineering to designate a specific variant of aluminium selected for a particular application. It describes a defined combination of alloy composition, temper (heat-treatment state) and often surface treatment, yielding a predictable set of mechanical and chemical properties. The concept is common in German-language technical literature and in internal design specifications that offer multiple aluminium options within a product family.

Variants are typically specified by alloy designation, temper, and any surface treatment. For example, a variant might use a 6000-series alloy such as 6061 with temper T6 for good strength and formability, while another variant might use a 5xxx or 7xxx-series alloy for higher strength or improved corrosion resistance. Surface treatments like anodizing or painting can further distinguish variants.

Property targets for a aluminiumvariante include strength-to-weight ratio, hardness, ductility, corrosion resistance, formability, and weldability. The chosen variant influences manufacturing routes (extrusion, casting, or sheet forming), heat treatment requirements, and recyclability. Cost, supply availability, and compatibility with other materials also guide the selection.

Note that aluminiumvariante is not a formal international designation; rather, it is a practical label used in specifications to compare alternatives. It helps engineers balance performance, manufacturability and cost across a product family. See also aluminium alloy, temper designation, surface treatment.
