You may want to reconsider the aluminum flashing. My experience is that ground contact it will last about 6 months. Here's a link to what the concrete industry says about aluminum.Bought some Termidor SC from domyown.com and mixed pretty strong and soaked the bottom of the hole for protection against termites. The guy that’s going to do my concrete told me to rap the post with aluminum flashing before he pours the concrete said it helps.

And copper and concrete don't mix either.
