Actually, silver oxide is conductive and is very soft. Aluminum oxide is

Thanks for the reply ! I will look into these
suggestions. I would like
an understanding of which types of metals would work best. It seems
that silver would work best, but it is very expensive. And there seems
to be adhesives, coatings and more solid types of different materials.
I suppose that aluminum wouldn't work as well as silver or copper. The
piece that the previous owner used has a silvery color to it. So it is
probably foil.
I would think silver would be the worst, as it tarnishes (corrodes) in
air.
