Notes:(1) Chemical compositions are referenced in AS/NZS 1866. Single figures are maximums.
(2) Mechanical properties and ratings for T5 & T6 temper is specified in AS/NZS 1866.
(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).
