The third volume of the aluminum pocketbook trio focuses on the further processing and application of aluminum materials. All information has been updated and adapted to the European standards system. The volume takes into account the interconnection of material properties, design, and application, highlighting the relationship between technological progress and new areas of application for aluminum. Based on an overview of the types of semi-finished products, the methods of machining aluminum are presented. An explanation of joining methods for aluminum forms the basis for the construction principles discussed afterward. Subsequently, the currently most important application cases of aluminum as a material are described. Numerous cross-references help locate potentially important fundamentals in the other two volumes.
