The invention relates to a heat-resistant aluminium alloy for heat exchangers, a method for producing an aluminium strip or sheet for heat exchangers, and a corresponding aluminium strip or sheet. The aim of the invention is to provide an aluminium alloy and an aluminium strip or sheet which has a good recycling capacity, a Solidus temperature of at least 620 °C, and an improved heat-resistance after welding. To this end, the inventive aluminium alloy comprises the following parts of alloy constituents in wt. %: 0.3 % <= Si <= 1 %, Fe <= 0.5 %, 0.3 % <= Cu <= 0.7 %, 1.1 % <= Mn <= 1.8 %, 0.15 % <= Mg <= 0.6 %, 0.01 % <= Cr <= 0.3 %, Zn <= 0.10 %, Ti <= 0.3 %, unavoidable impurities separately representing a maximum of 0.1 %, and together a maximum of 0.15 %, the remainder being aluminium.
