Notes:(1) Chemical compositions are referenced in AS/NZS 1866. Single figures are maximums.
(2) Mechanical properties and ratings for T1, T4, T5 & T6 tempers are specified in AS/NZS 1866. H81 temper is specified in AS/NZS 1867 as T81 temper. Temper F is included in BS 1474 and is given for information only.
(3) Thickness is defined as the diameter of solid rod or the wall thickness or the equivalent major solid cross section.
(4) Yield is based on 0.2% Proof Stress.
(5) Elongation is based on 50mm test parameter.
(6) Ratings A through E are relative ratings in order of merit for the hardest temper (A = Excellent E = Poor).
Consult McKechnie Aluminium Technical Services Department if further information is required.
