5052 aluminium alloy

5052 is an aluminium–magnesium alloy, primarily alloyed with magnesium and chromium. 5052 is not a heat treatable aluminum alloy, but can be hardened through cold working.

Chemical properties
The alloy composition of 5052 is:
 * Magnesium - 2.2%-2.8% by weight
 * Chromium - 0.15%-0.35% maximum
 * Copper - 0.1% maximum
 * Iron - 0.4% maximum
 * Manganese - 0.1% maximum
 * Silicon - 0.25% maximum
 * Zinc - 0.1% maximum
 * Remainder Aluminium

A similar alloy A5652 exists differing only in impurities limits.

Uses
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.
