Abstract

Brilliancy and polish are imparted to articles of aluminium or aluminium alloys by immersing them in a bath consisting of concentrated phosphoric, nitric and sulphuric acids together with a weak acid which forms a complex with phosphoric acid. The weak acid may be molybdic, iodic, vanadic, boric or tungstic and hydrochloric and acetic acids may also be present.
