Further background information on these products is in "Aluminium Standards, Data and Design" published by the Aluminium Council of Australia and in "Aluminium Standards and Data" published by the Aluminium Association (USA). The following alloys are those commonly stocked in the Atlas Steels Aluminium flat products program.   [b]Alloy Code Derivative[/b] Alloy series Major alloying element 1??? Pure aluminium (99.0% and greater) 2??? Copper is major addition 3??? Manganese is major addition 4??? Silicon is major addition 5??? Magnesium is major addition 6??? Magnesium and silicon are major additions 7??? Zinc is the major addition 8??? Other Alloys   [b]Understanding an Alloy code [/b]An alloy code is made up of 4 digits e.g. 5052 where: 5 = major alloying element i.e. magnesium 0 = Indicates changes to minor alloying elements i.e. no changes to original alloy since it was introduced 52 = Alloy identification number i.e. identifies the chemical composition of this alloy   [b]Alloy Code derivative used in Rolled Products[/b] Alloy Example Alloy 1??? 1145 3??? 3003 5??? 5052   [b]Heat Treatable and Non-heat Treatable Alloys[/b] Alloy Treatable/Non-treatable 1??? Non-heat treatable 2??? Heat treatable 3??? Non-heat treatable 5??? Non-heat treatable 6??? Heat treatable 7??? Heat treatable Non-heat treatable alloys can be hardened by cold work. The degree of work hardening is designated by the Temper. Heat treatable alloys (the 2000, 6000, and 7000 series) are able to be solution treated and then age-hardened.   [b]Temper Designation Systems[/b] [b] H Tempers[/b] Temper Hardness 0 Soft H?2 1/4  hard H?4 1/2 hard H?6 3/4  hard H?8 Hard Where "?" can be read as: 1 = As rolled - no final anneal e.g. H12 2 = Strain hardened and then partially annealed e.g. H24 3 = Strain hardened and then stabilised (at a lower temperature) e.g. H34 [b]Three-Digit H Tempers [/b]For marine applications there are specific tempers in select high magnesium alloys.  Atlas stock is of alloy 5083, usually in H116 temper.  An alternative is H321 with virtually identical properties.  H116 tempers are strain hardened as a final opearation and H321 tempers are thermally stabilized.
