Aluminium is the most used metal to produce light and highly stressed castings. Due to its good castability and low specific mass, the automotive sector in particular offers many fields of application. Furthermore, it is ideal for food industry because of its low corrosion tendency.

All applications require specific metallurgic treatments including cleaning of the metal, grain refinement as well as modification. Only a specific treatment of the melt results in properties such as high strength, high extension values and secured anodisability. The treatment of the dross is also very important, as there is a huge saving potential of recovered metal and furnace and crucible walls need special maintenance.
