Use Galvanized shackles with galvanized chain. If you had a stainless anchor
and chain, then you would use stainless shackles.
The aluminum anchors are anodized. Are there stainless screws holding parts
of it together? You might try bedding the stainless screws in caulk to cut
down on the corrosion between the aluminum and stainless. If you can find
them, I would replace the stainless screws with galvanized, or just use
plain steel screws and spray them with cold galvanizing compound.
Incidentally, every anchor I ever purchased, I first spray them down with
cold galvanizing compound. This seals the surface off, then when the hot
galvanizing starts to show through, I simply re-spray the anchor. My anchors
have always looked great that way.
I happen to have an anodized aluminum traveler that is 14 years old. There
are stainless screws in the screw holes. HOWEVER, the holes are anodized so
there was no corrosion on the screws and they were easy to remove. They were
never immersed in salt water though.
