Atlas Aluminium datasheet 5052 rev Oct 2013 - …

1 Aluminium AlloyData Sheet5052 Revised October 2013 Page 1 of 5052is a non-heat-treatable 2 %magnesium, chromium alloy commonlyavailable in flat rolled coil, sheet and plate froma wide range of producing mills. Like all the5000-series high magnesium alloys 5052 has afairly high strength and is hardenable to asignificant degree by cold working, enabling aseries of H 5052 is also produced as a treadplate(also known as chequer plate) with mainlyindustrial finish sheet is produced typically in alloy is also produced as drawn seamlesstube, wire and bar and foil, available on indentfrom ResistanceExcellent in a wide range of atmosphericenvironments, infoodandarchitecturalapplications and it is also acceptable in manymarine environments.

2 The magnesium contentis low enough that it does not suffer from thestress corrosion cracking that can affect alloyswith more than about 3 % Mg, such as TreatmentAlloy 5052 is not hardenable by heattreatment. It can be significantly hardened bycold work (eg by cold rolling) and various H tempers are produced most commonly H32( Hard) and H34 ( Hard) as well as thesoft annealed Temper O alloy spontaneously age-softens at roomtemperature immediately after cold work butwill eventually reach a stable condition; all flatrolled mill products are supplied with stableproperties.

3 This is usually achieved by astabilisation thermal treatment, either a lowtemperature thermal treatment or as a resultof heat introduced during rolling, which resultsin the H3x tempers. H2x tempers are moreseverely strain hardened and then partiallyannealed, again to quickly reach the requiredstable temper soften Alloy 5052 it can be annealed byheatingto345 C,holduntiluniformtemperature then cool; the rate of cooling isnot weldability by all standard methods;gas, electric and resistance welding.

4 GMAWand GTAW are preferred and widely used toproduce structural welds. Filler alloys areusually 5356 although other filler alloys arepossible. Welding of strain hardened temperswill reduce strengths in the heat of the softer tempers O and H32is poor, with the harder tempers such as H34being somewhat easier to 5251 AlternativeIt has become common practice in Australiaand New Zealand for Alloy 5251 to be offeredas an alternative to 5052 . The two alloys arevery similar in composition and properties andinmanycasestheyarefunctionallyinterch angeable.

5 They are however differentalloys and a piece of metal that complies withone cannot also comply with the other. Someusers can only accept one alloy or the of these alloys must decide whetheralternatives are ApplicationsSmall marine craft ( tinnies ), food processingequipment, cabinets, and in treadplate form isused for industrial and marine flooring, trailersand tool boxes.

The commonapproach is to specify as astm B209 in Alloy5052 and Temper O, with mechanical propertiesas on page 2 of this datasheet .
