Re: Searching for Electode Material

The resistivity of zinc is about 2.5 times that of copper. melting point is
419.58deg C (copper 1084.5). Zinc actually oxidises in air at a far lower
temperature than this. Brass bolts and studding should be available from
many engineering suppliers, also try a boatyard or chandlers.
