5052 is the aluminum alloy most suited to forming operations, with good workability and higher strength than that of either 1100 or 3003. 5052 is not heat-treatable, but is stronger than most of the 5xxx series of aluminums. It has very good corrosion resistance, and can be easily welded as well. 5052 is not a good choice for extensive machining operations, as it has only a fair machinability rating. It is typically used in aircraft fuel and oil lines, fuel tanks, sheet metal work, appliances, lighting, wire, and rivets.
