Atlas Aluminium datasheet 3003 rev Oct 2013 - Atlas Steels

1 Aluminium AlloyData Sheet3003 Revised October 2013 Page 1 of 3003is a non-heat-treatable , copper alloy commonlyavailable in flat rolled coil, sheet and plate froma wide range of producing mills. It is one of themost commonly used of all Aluminium alloys,essentially commercially pure Aluminium withthe addition of manganese to increase itsstrength about 20%. It has all the excellentproperties of alloy 1100; excellent corrosionresistance plus the ability to be easily drawn orspun, welded or brazed. Alloy 3003 is fairly lowstrength but it can be hardened to a significantdegree by cold working, enabling a series of H 3003 is also produced as a bright finishtreadplate (also known as chequer plate) withindustrial and decorative alloy is also produced as drawn orextruded seamless tube, forgings, wire and barand foil; these forms are available on indentfrom 3003 is also available as an Alclad product with one or both sides clad in Alloy7072; again available on indent from ResistanceExcellent in a wide range of atmosphericenvironments, TreatmentAlloy 3003 is not hardenable by heattreatment.

2 It can be significantly hardened bycold work (eg by cold rolling) and various H tempers are produced most commonly H12( Hard) and H14 ( Hard) as well as thesoft annealed Temper O 3003 is usually supplied in H1x tempers,where the product is strain hardened only;there is no stabilisation treatment as is usualfor the 5xxx series soften Alloy 3003 it can be annealed byheatingto415 C,holduntiluniformtemperature then cool; the rate of cooling isnot weldability by all standard methods;gas, electric and resistance welding. GMAWand GTAW are preferred and widely used toproduce structural welds. Filler alloys areusually 1100 although other alloys arepossible. Welding of strain hardened temperswill reduce strengths in the heat of the softer tempers O and H12is poor, with the harder tempers such as H14and above being somewhat easier to in alloy 3003 is typically used indecorative architectural applications, due to itsbright reflective finish.

3 It is usually produced ina 1-bar or propeller tread pattern. Alloy3003 treadplate is available on indent Applicationscooking utensils, decorative trim, awnings,siding, storage tanks, chemical AlloyData Sheet3003 Revised October 2013 Page 2 of PropertiesThese properties are specified for flat rolled product (plate, sheet and coil) in ASTM but not necessarily identical properties are specified for other products such as tube andbar in their respective Specification (%)(single values are maxima except as noted) Property Specification(single values are minima except as noted)Elongation(% in 50mm)minimum for sheet or plate thicknesses shownAlloy&TemperTensileStrength(MPa)Yie ld Proof(MPa) - 1303518202325233003-H12120 - 16085-3469 *3003-H14140 - 18011512358 *3003-H16165 - 2051451234 *-3003-H18185 min1651124 *-Tempers H22 and H24 etc may not meet maximum tensile strength and minimum yield strength limits,but if supplied in place of ordered H12 or H14 all limits must be complied with.
