I like the using all aluminum idea, thanks CoryPad. DO I need to take precautions for the 2000 series stuff to protect against corrosion and what about crevice corrosion?
Im designing a solar tracking frame that needs to be corrosion resistant for installations in coastal areas and UV resistant.
I am using 6061-T6 aluminum for the frame members.
There is an EPDM gasket between members to avoid crevice corrosion
I am securing the frame members together with 18-8...
