ABSTRACT:
A rapid and effective surface cleaning process for copper alloys, particularly copper alloys containing aluminum and other metals tending to form surface coatings of refractory oxides during annealing treatments, consists of treating such alloys or articles fabricated thereof for a short time in a hot aqueous solution of an alkali hydroxide, rinsing with water, and then immersing for a short time in a hot aqueous solution of ferric sulfate, or other ferric salt of a mineral acid, followed by rinsing with water.
