Rheinfelden Castasil-37 (AlSi9MnMoZr) is an aluminum-silicon-manganese-molybdenum-zirconium high pressure die casting (HPDC) alloy. It was developed by Rheinfelden Alloys GmbH for the production of large and complex high pressure die castings for automotive structural applications. This alloy is used in the as-cast condition, and exhibits good mechanical properties, especially elongation, which are superior to those of conventional aluminum-silicon alloys. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as casting, heat treating, and joining. Filing Code: Al-481. Producer or source: Rheinfelden Alloys GmbH & Co. KG.
