Three words sum it up: progress in aluminum.
The Salzburger Aluminium Group (SAG Group) integrates innovative lightweight construction into vehicle construction, thereby helping to cut CO2 emissions. When sleek sports cars or high-end automobiles accelerate to sixty miles per hour in just a few seconds, lightweight rheocasting components from Austria are playing their part. Heavy goods vehicles also benefit from advanced lightweight components made by the SAG Group. They are welded using patented Cold Metal Transfer and WireSense technology from Fronius.
The SAG Group traces its origins back to Salzburger Aluminium AG, founded in 1898, and today employs around 1,100 people at nine locations in Europe, Mexico, and the US. The production sites in Austria are located in Lend and Schwarzach, not far from the provincial capital of Salzburg and around 200 km from Munich. As a leading manufacturer of aluminum tanks for heavy trucks, SAG is a global supplier for many well-known OEMs. Other products include lightweight components for carriages, air reservoirs, air pressure tanks and special components for the car, commercial vehicle, rail, and special vehicle industries.
Special rheocasting technology for the manufacture of highly robust lightweight components was brought to series maturity by the SAG Group after years of research. With this method, aluminum is not processed in a completely liquid state, as in conventional casting processes, but in a semi-solid or semi-liquid form and then turned into lightweight components for the automotive industry. The laminar, almost turbulence-free filling process prevents unwanted gas inclusions during casting. Cavities, so-called shrink holes, are sealed by shrinkage of the solidifying melt. This makes rheocasting components very easy to weld due to their low porosity.
