Galvanic Corrosion between A7050 and A2024 and A7075

[iamchoyh]

Hi..

I was searching the galvanic table from Mil-Std-889.
But, there are no information of the other al-alloy.
(ex:A7050...)
If I select the other al-alloy, Is it safe?
I don't think like that...
and There isn't showing the effect of heat-treat...

I need the informations...

Thank a lot.
