ALUMINUM 413.0 is normally classified as a die-casting alloy; however, it also can be used for sand and permanent-mold castings. Its high silicon content (12%) lowers its melting temperature and increases its fluidity, thus improving its castability. It is used for intricate thin-walled castings requiring pressure tightness, toughness and good resistance to corrosion. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness and fatigue. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Al-231. Producer or source: Various aluminum companies.
