Conductivity of Zinc Cobalt Plating

Can any one give accurate conductivity comparisons between olive drab cadmium and zinc cobalt as a finish plating.
Opinions seem to differ on this point and I would appreciate informed views.

Hope this helps you.
Cadmium has a conductivity of 1.462E+07 siemens/m
Zinc-cobalt - 1.670E+07 siemens/m (depending on the exact alloy plated)
Pure silver - 6.287E+07 siemens/m (provided as an example)
The Zn-Co alloy would have a higher conductivity rating.
