Not the can itself, Curt, but the LID! It's stamped aluminum on the brand I buy (Weis decaf, 33 oz. tin), with an embossed checkerboard-like pattern. Disclaimer: I've never tried to make a diaphragm out of this (or any other) material; I merely referenced what I remembered from another thread!

Coffee cans today have the pull-off type lids, and typically are sold with a plastic lid to be used once the pull-off lid is removed. Gone are the cans with lids made from the same material as the cans themselves.

Henry,
I think I'm on the same page, now... You are talking about the thin metallic peel off seals on coffee cans, right? They may work very well...

Right, Curt. Peel-off lid.

Weis (one "s," pronounced "wise") is a grocery store chain based in PA, with stores also in MD and NJ, I think. They compete with such as Giant, Acme, Wegman's, et al. Down your way it would be Winn-Dixie, Bi-Lo, Publix, etc.
