| 摘要 |
The invention relates to a solderable, three-layered aluminium composite material comprising at least three layers consisting of at least two different aluminium alloys, wherein an inner layer of the at least three layers is an aluminium solder layer consisting of an aluminium solder alloy and the other layers are in the form of outer layers and consist of at least one further aluminium alloy, wherein the at least one further aluminium alloy has a solidus temperature which is higher than the liquidus temperature of the aluminium solder alloy. The object of providing a solderable aluminium composite material which has a simple structure, has good soldering properties for producing I-shaped butt-soldered joints, considerably reduces the risk of soldered components "burning through" and also provides sufficient mechanical properties is achieved by virtue of the fact that the individual outer layers (2, 4) have a thickness which exceeds the thickness of the aluminium solder layer (3) by at least a factor of 1.5, preferably at least by a factor of five. |
