Hi everyone,
I'm supposed to manufacture a part in Alclad L73 (British Standard aluminium alloy), does anyone know an alternative material to it?
Does somebody knows where to find its mechanical properties (of L73)?
Thanks,
PireX
L 73 is a BS specification cladded aluminum sheet solutionised and precipitation hardened for aircraft sheet metal component manufacture.
2014 T6 replaces BS L 73.
2024 T3 is also widely used as replacement.
Both 2024 and 2014 are identical in most respects.
I would prefer 2024 as this is most commonly used material and availability is wide spread. Another advantage being 2024 need not be Precipitate hardened to achieve maximum mechanical strength equivalent to BS L73. The material will naturally age in the open atmosphere to attain maximum tensile strength of T6 condition.
