Rio Tinto C355.2 is a heat-treatable, aluminum-silicon-copper-magnesium casting alloy (3xx.x series). It is available in the form of ingots for remelting, to be used for the production of sand and permanent mold castings. Alloy C355.0 is a higher purity, low iron version of alloy 355.0. Both the alloys are similar, except the lower iron in C355.0 provides better elongation and somewhat higher tensile strength. Alloy C355.0 is used in premium, high strength applications where castings are usually heat treated for maximum strength. 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-490. Producer or source: Rio Tinto Limited.
