High-strength solder-plated al-mg-si aluminum material

Abstract

The invention relates to an aluminium material for the manufacture of high-strength, soldered components comprising an aluminium alloy of the type AlMgSi, in particular of the type AA6xxx, wherein the aluminium material is at least in some areas directly or indirectly in materially-bonded contact with at least one solder layer after soldering. The object of providing an aluminium material which not only provides good soldering properties and good formability, but also provides high strength, is achieved in that the aluminium alloy of the aluminium material has a solidus temperature Tsol of at least 595° C. and the aluminium material has an increase in the yield strength Rp0.2 compared to the state after soldering of at least 90 MPa, preferably at least 120 MPa, after soldering at at least 595° C. and cooling at an average cooling rate of at least 0.5° C./s from 595° C. to 200° C. and an artificial ageing at 205° C. for 45 minutes.
