Abstract
The composite article includes a core layer of an aluminium alloy. This core layer is arranged between two outer layer portions which are structured as mere images of each other relative to the core layer. Such an outer layer portion may include a layer of pure aluminium arranged on the core layer followed by a layer of carbon steel and finally a layer of an austenitic high-grade steel forming the outermost layer. This composite article has an excellent heat conducting property and is easily magnetizable. The arrangement of the individual layers does not lead to difficulties such as detaching of layers, rupturing of layers or the forming of waves during a cold deforming, drawing etc. of the composite article.
