If you're struggling with the contact problem, replace the
aluminum surfaces with thin stainless steel sheet. It
won't cost much for the area you've got, thin sheet can
be cut with tinsnips, and it won't oxidize. There
are other materials that will work, too, but stainless
sheet is easily available. The aluminum oxide coating
that forms on aluminium is a poor conductor.
For contact brushes, copper wire brushes would be good.
