The mechanical properties of alloys 6060-T5 and 6082-T5,T6 are not shown in the Australian Standard AS1664 (The Structural Use of Aluminium). What should I do?
The guaranteed minimum mechanical properties of 6060-T5 are the same as for the alloy 6063-T5. Therefore use the 6063-T5 data in AS1664 for alloy 6060-T5.
With regard to alloy 6082 it has a chemical composition which overlaps that of alloy 6351 and the guaranteed mechanical properties are essentially the same. Therefore use the 6351 data in AS1664 for alloy 6082.
