Depending on the wide range of aluminum alloying systems and the substantial number of different fields of usage, secondary alloys can contain a high number of alloying elements and impurities. From an economic standpoint, it is impossible to remove these elements completely. These elements could, however, influence the cutting and anodizing abilities of the material. Therefor the aim of this work is to extend the basic knowledge about these influences and the occurrence of interactions between alloying elements and impurities. By using the software Modde for experimental design, the best processing parameters from different cutting procedures (e. g. cutting speed, usage of lubricants, etc.) are investigated. The experimental set-up was chosen to generate high surface qualities at low process costs. In the second part of the thesis, the anodizing behavior of different alloys is analyzed.
