Rheinfelden Anticorodal-04 (AlSi0.5Mg) is a heat-treatable aluminum-silicon-magnesium casting alloy that is used for applications requiring medium strength, excellent electrical conductivity, and excellent corrosion resistance. This alloy is, however, difficult to cast owing to its low silicon content. 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-487. Producer or source: Aluminium Rheinfelden Alloys GmbH.
