FEDERATED F430 is a heat-treatable aluminum-copper-silicon casting alloy with good castability, machinability and corrosion resistance. It is produced by sand casting and is a general-purpose alloy recommended in both the as-cast and heat-treated conditions. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Al-118. Producer or source: Federated Metals Corporation, ASARCO Inc..
