GALFAN is a zinc-5% aluminum alloy with an addition of mischmetal to introduce small amounts of the rare-earth elements lanthanum and cerium. Its composition is eutectic and it was developed to provide a hot-dip coating alloy that would be better than zinc as a protective coating for steel. GALFAN can be used to coat steel sheet, strip and wire with only minor modification of the existing equipment used to produce galvanized steel. GALFAN coatings have good performance characteristics in a variety of applications. This datasheet provides information on composition, physical properties, and hardness. It also includes information on corrosion resistance as well as heat treating and joining. Filing Code: Zn-40. Producer or source: Zinc Research Organization Inc..
