Data sheet AA5754

General properties

Aluminium-magnesium alloy, general purpose, whose main properties are very high resistance to oxidation and corrosion in general; mechanical strength is low, cold formability is good; fusion weldable.
Generally used in form of sheet.

Ex stock the following tempers are available

Other tempers can be delivered on demand.

Typical applications

Skins, pressure vessels, tanks and trucks, shipbuilding, chemical plants, plates, wheels, cryogenic applications, applications for which moderate static strength are required.

Parts to be embodied into welded structures.
