Solution annealing, quenching and artificial ageing

Due to its low density and very good strength properties, aluminium is the preferred material for lightweight construction, for both rail and road as well as for aviation. This applies for both cast and formed components. Depending on the application, the targeted properties are high strength and ductility in the chassis area and structure, as well as thermal resilience in the region of the motor.

The basic prerequisites for these properties are determined by chemical composition, metallurgical treatment and casting procedure. However, heat treatment has a particularly significant impact on the characteristics of the casting.
