Antimony concentration vs. conductivity of silver


(1996)

Does anyone know the correlation between Antimony concentration in silver deposit and conductivity of silver?

Some background: Lowenheim's Electroplating textbook, page 261, says, unquote:... antimony has been recommended as a hardener for silver deposits... Antimony will harden silver deposits... , quote: "but there is considerable disagreement about whether hardness and wear resistance necessarily go together", unquote.

I'll bet a coffee that the small amounts of antimony probably needed for hardening will be undetectable in conductivity measurements.

Make the bet a beer and I'll double it, Tom. Although I couldn't quickly find a chart with the conductivity of silver vs. antimony concentration, a quick look through conductivity tables for other metals showed that even a very minor amount of alloying material drastically cuts down on conductivity (probably because the crystal lattice dislocations disrupt the travel of the electron 'cloud').

But the conductivity of a solid material like a silver wire and the surface resistance of silver plating are different things. It's possible that the antimony has no effect or even a positive effect on the contact resistance of a silver plated connection.
