Dear Tim,

I have had your request in mind, but I haven't come across the specifications until this afternoon. I just looked through a copy of the latest Aluminium-Schlüssel (2002-edition), and according to them the composition limits for 5025 are as follows (all numbers are wt.%):

Si: 0.25 max
Fe: 0.25 max
Cu: 0.10 max
Mn: 0.20 max
Mg: 4.5 - 6.0
Cr: 0.20 max
Zn: 0.25 max
Ti: 0.05 - 0.20
Zr: 0.10 - 0.25
Be: 0.0008 max
Sc: 0.05 - 0.55
Others, each: 0.05 max
Others, total: 0.15 max

I hope this is still of interest.

Best Regards,
Jostein Røyset
