1 Aluminium AlloyData Sheet5005 Revised October 2013 Page 1 of 5005is a non-heat-treatable alloy commonly available in flatrolled coil, sheet and plate from a wide rangeof producing mills. The 5000-series magnesiumalloys have a high strengths because of themagnesium addition; 5005 has only a verysmall addition of magnesium so is the leaststrength of these series of alloys. The alloy ishardenable to a significant degree by coldworking, enabling a series of H tempers butagain these do not achieve the high strengthsof corresponding tempers in other alloys suchas 5052 or alloy is also produced as strandedconductor, drawn seamless tube, wire and bar,available on indent from ResistanceExcellent in a wide range of atmosphericenvironments, in architectural applications.
2 Themagnesium content is low enough that it doesnot suffer from the stress corrosion crackingthat can affect alloys with more than about3 % Mg, such as TreatmentAlloy 5005 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 5005 it can be annealed byheatingto345 C,holduntiluniformtemperature then cool; the rate of cooling isnot Aluminium alloys can be anodised toimprove corrosion resistance, but decorativeanodising is only carried out on a few most commonly decoratively anodisednon-heat-treatable alloy is 5005.
4 It is producedas a special anodising quality (AQ) but Atlasdoes not stock this product. It is most commonand usually successful for general purposequality (non-AQ) to be anodised; this canhowever result in some visually inconsistentanodising outcomes and in severe cases in tiger stripe appearance. It is alwaysrecommended that anodising performance betested by trialling a piece from a batch sheets can be sourced on indent if requiredfor critical anodised, film on 5005 is clearer andlighter than on 3003 and gives better colourmatch with 6063 architectural weldability by all standard methods;gas, electric and resistance welding.
5 GMAWand GTAW are preferred and widely used. Filleralloys are usually 4043 although other alloysare possible. Welding of strain hardenedtempers will reduce strengths in the heataffected is poor, with the harder temperssuch as H34 and above being somewhat easierto ApplicationsElectrical conductor wire, cooking utensils,appliances and widely used as sheet inarchitectural AlloyData Sheet5005 Revised October 2013 Page 2 of PropertiesThese properties are specified for flat rolled product (plate, sheet and coil)
