Abstract Rheinfelden Castasil-21 (Ci-21, AlSi9Sr) is an aluminum-silicon-iron-strontium high pressure die casting (HPDC) alloy. It was developed by Rheinfelden Alloys GmbH and Co. KG for castings that require an outstanding combination of electrical and/or thermal conductivity. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Al-476. Producer or source: Rheinfelden Alloys GmbH.

Pressure Die Casting

In this work we found that the addition of excess Mg can significantly improve the mechanical properties of pseudo-binary Al-Mg2Si alloys after high pressure die casting (HPDC). Al-8Mg2Si-6Mg alloy offered an excellent combination of high strength and reasonable ductility. Excess Mg lowers the Mg2Si content in the eutectic reaction and promotes the formation of Mg2Si as the primary phase, and this is believed to be the origin of improved mechanical performance.
