Single solution Non-Cyanide based for Electroplating
« on: December 19, 2023, 10:40:05 PM »
I've been trying to search for a possible non-cyanide based solution to plate the following metals:

Au (Gold)
Ag (Silver)
Rh (Rhodium)
Pt (Platinum)
Pd (Palladium)
Cu (Copper)
Ni (Nickel)
Co(Cobalt)
W (Tungsten)

Has anyone tried experimenting on plating these metal with a single non-cyanide solution? I know its a bit challenging due to these metals different properties but would it be possible ???
