Document Type and Number:
Japanese Patent JP2007530794
Kind Code:
A
Abstract:
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 wL %: 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.
