Plated aluminium tubing gives corrosion resistance Available to Purchase

The Société Métallurgique de Gerzat has perfected a manufacturing process for aluminium tubes plated on the inside, outside or simultaneously on both surfaces. For A5, A‐M1 (American 3003) and A‐G1 tubes, the plating is carried out with a 2% zinc aluminium alloy which provides protection by electro‐chemical means of the bore of the tube against corrosion in aggressive ambients, particularly those involving running water. The tubes are produced by direct pouring methods, without any welding whatsoever. The plating, therefore, faithfully follows all the deformations which might occur in the tubing and thus maintains all its properties. The tubes can be supplied either tempered or drawn (types varying from ¼ hard to ¾ hard). The range of external diameters varies from 10 to 100 mm., the thicknesses from 0.4 to several millimetres. The thickness of the plating ranges from 0.15 – 0.3 mm. The Société Métallurgique de Gerzat is represented in Britain by Monogram Engineering Services Ltd., Clarendon Road, Watford, Herts.
