ALUMINUM 518.0 is an aluminum die-casting alloy with an excellent combination of high strength and resistance to corrosion. It also has high ductility, good polishing characteristics, poor castability (it is hot short) and excellent machinability. Its uses include marine fittings, ornamental hardware, outboard motor brackets and ornamental automotive parts. 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, forming, heat treating, machining, and joining. Filing Code: Al-242. Producer or source: Various aluminum companies.
