Abstract:
    The invention provides insulated aluminium wire in which the insulation comprises either a single layer of barrier-layer (non-porous) anodic aluminium oxide, or two layers, an inner barrier-layer anodic oxide film and an outer layer of hydrated alumina. The insulated wire may be made by continuously anodizing wire of Al or an Al/Mg alloy in a barrier-layer electrolyte such as tartaric acid, and then exposing the anodized wire to hot water to partly hydrate the anodic oxide film.
