Why Rhodium?

Rhodium is an excellent conductor of electricity, it resists oxidation, has low and stable contact resistance, and high corrosion resistance.

Waste of money. Recently rhodium commodity prices have sky rocketed, so it falls into the hi-end trap of 'more expensive, must be better'. A friend, who is a material scientist with a PhD, tells me its electrical properties suggest it worsens current flow. You figure.

Buconero, you'd better have your friend call George Cardas and tell him, since he is pretty big advocate of Rhodium...
