Alcoa A354 VersaCast is a proprietary, heat-treatable, Al-Si-Cu-Mg casting alloy (3xx.x series). Owing to its high strength, high ductility, and very good casting characteristics, it is used for the most demanding structural applications. It also is used as a costeffective alternative to ductile iron castings. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting. Filing Code: Al-473. Producer or source: Alcoa Corporation.
