Abstract

Die Erfindung betrifft eine kaltaushärtbare Aluminiumlegierung für Wärmetauscher, ein Verfahren zur Herstellung eines kaltaushärtbaren Aluminiumbandes sowie ein Aluminiumband oder -blech. Die Aufgabe, eine kaltaushärtbare Aluminiumlegierung für Wärmetauscher zur Verfügung zu stellen, welche den wirtschaftlichen Einsatz des Schutzgaslötens bei der Herstellung von Wärmetauschern ermöglicht und gleichzeitig hohe Festigkeitswerte nach einer Kaltauslagerung nach dem Löten aufweist, wird dadurch gelöst, dass die Aluminiumlegierung folgende Legierungsanteile in Gew.-% aufweist: Si ≤ 0,7%, 0,1% ≤ Mg ≤ 0,3%, Fe ≤ 0,3%, Cu ≤ 0,2%, Ti ≤ 0,2%, Mn ≤ 0,1%, Cr ≤ 0,1%, Zn ≤ 0,1%, unvermeidbare Begleitelemente einzeln max. 0,1%, in Summe max. 0,15% und als Rest Aluminium.The invention relates to a cold-hardenable aluminum alloy for heat exchangers, a method for producing a cold-hardenable aluminum strip and an aluminum strip or sheet. The object of providing a cold-hardenable aluminum alloy for heat exchangers, which enables the economic use of inert gas soldering in the production of heat exchangers and at the same time has high strength values after cold aging after soldering, is achieved in that the aluminum alloy has the following alloy proportions by weight. % having: Si ≤ 0.7%, 0.1% ≤ Mg ≤ 0.3%, Fe ≤ 0.3%, Cu ≤ 0.2%, Ti ≤ 0.2%, Mn ≤ 0.1%, Cr ≤ 0.1%, Zn≤0.1%, unavoidable accompanying elements individually max. 0.1%, in total max. 0.15% and the balance aluminum.
