The electrodeposition of aluminum in the form of white or shiny adherent plates on various metals has been accomplished at room temperature. A satisfactory plating solution is prepared by mixing two moles of anhydrous aluminum chloride with 1 mole of ethyl pyridinium bromide, preferably in a dry, oxygen‐free atmosphere, to produce a liquid to which benzene (or toluene) is added until a second layer, principally excess benzene, forms on the top of the plating solution. Using an aluminum anode, plating may be carried out in a protected atmosphere at cathode current densities of approximately 1 amp/dm2 (about 9 amp/ft2) using voltages of the order of one volt.
