About 5052 Aluminum - Aluminum alloy 5052 in H32 temper has very good corrosion resistance to seawater and marine and industrial atmosphere. It also has very good weldability and good cold formability. It is a medium to high strength alloy with a strength slightly higher than 5251 and a medium to high fatigue strength. Typical applications include marine, aircraft, architecture, general sheet metal work, heat exchangers, fuel lines and tanks, flooring panels, streetlights, appliances, rivets and wire. The exceptional corrosion resistance of 5052 alloy against seawater and salt spray makes it a primary candidate for the failure-sensitive large marine structures, like tanks of liquefied natural gas tankers.
