A silver electroplating procedure is disclosed which permits rapid and efficient plating and yields ductile, adherent silver films. The electroplating bath comprises silver complexed with an aliphatic polyamine compound with 3 to 20 carbon atoms. Particularly useful are such polyamines as diaminopropane (particularly 1,3-diaminopropane), diethylenetriamine, 1,4-diaminobutane, 1,6-diaminohexane, etc. The procedure is also useful for electroplating a variety of silver alloys. In addition, the bath is highly stable, does not adversely affect the base material being plated and does not contain hazardous materials which require special disposal procedures.
