Hello,
I'm doing some research on aluminium and have come across some alloys of which i need 'equivalent' names for, in today's standard nomenclature (1xxx,2xxx,3xxx and so on).
The alloys I have are H30-WP and H15-WP.
Also, with some early NACA tests (1940's) on 24S-T, 17S-T and R303-T sheet and extrusions... I realise that these are 2024 and 2017 alloys but there is no indication of the temper. (Other than the obvious 'thermal').
Any direction would be great,
Regards,
James
