Aluminum has a very tenacious oxide coating, but if it is reduced, tin-lead will wet it, I believe. This may be an old address, but try these people who used to sell Almit: Seika Corporation 20000 Mariner Ave., #100 Torrance, CA 90503 213-373-0404 This is by no means an endorsement of interconnecting boards with aluminum wire.
