Obscure Metals

I ordered from Amazon, a sheet of solid tin, which when it arrived was tin coated steel.  RotoMetals has all sorts of exotic metals: tin; gallium; indium; lead; bismuth; and cstuff that makes me scratch my head: crab shrimp pot anode?


  1. Just like a zinc anode for a boat, to offer a sacrificial metal for electrolysis.

    Particularly in salt water, dissimilar metal corrosion is a big issue so a cheap, easily replaced and non-noble metal is offered up.

    On my boats, for instance, I'd much rather replace an anode than the prop or prop shaft (which are different metals, and touching)

  2. Could be like the anode in a hot water heater, to keep the pot from corroding?
