Title: Bath and method for the electrodeposition of bright nickel-iron deposits

Abstract: A nickel-iron alloy plating bath containing nickel ions and iron ions, a soluble non-reducing complexing agent, and a reducing saccharide selected from the group consisting of monosaccharides and disaccharides. The combination of hydroxy carboxylic acid complexers and reducing saccharide in such baths yielding high iron content bright level nickel-iron alloy deposits containing up to 50 percent iron, while retaining the Fe.sup.+.sup.3 concentration in the bath at a minimum value and reducing the amount of complexers which is required. Generally, it is preferred to utilize from about 1 to about 50 grams per liter of a reducing saccharide and from about 2 to about 100 grams per liter of the complexing agent.
