Galvanoplastic deposition of a gold alloy on an electrode dipped into a bath including gold metal in alkaline aurocyanide form, organometallic compounds, a wetting agent, a sequestering agent and free cyanide, where the alloy metal is copper, which is in double copper and potassium cyanide form, and silver, or in cyanide form, comprises depositing a mirror-bright yellow gold alloy on the electrode, where the bath respects a proportion of 9.08% gold, 90.85% copper and 0.07% silver containing neither cadmium nor zinc. Independent claims are also included for: (1) an electrolytic deposition in the form of a gold alloy obtained from the above method having a thickness of 1-800 mu and comprising copper and silver as the third main compound, allowing a bright 3N color to be obtained; and (2) an electrolytic deposition is in the form of a gold, copper, and silver alloy, where the deposition is made of gold (75%), copper (21%) and silver (4%), allowing a bright 3N color to be obtained. |
