An electrochemical method for the extraction of precipitates from age-hardenable aluminium alloys has been developed. Small anodic currents of ~10 mA cm-2 are applied to samples suspended in a methanolic electrolyte containing benzoic acid, oxine, and chloroform. An analysis of extractions made using different current densities shows that the principal function of the anodic current is to break down the aluminium oxide film. The method should have considerable application in the study of high strength aluminium alloys
