The process for degassing aluminum and aluminum alloys comprising treating the molten metal with a gaseous mixture consisting essentially of fluorine, hydrofluoric acid, carbon monoxide and carbon dioxide. Fluorine, hydrofluoric acid, carbon monoxide and carbon dioxide are produced during the electrolytic reduction of alumina to form aluminum, therefore, the gaseous mixture resulting from this electrolytic reduction may be used to degas aluminum and aluminum alloys.
