§ Mr. Harold Walkerasked the Minister of Technology what advice he has given to electrical manufacturers about the use of substitute metals for copper in electrical conductors; and if he will accelerate research into this subject.
§ Mr. BennNone. The Trade Associations concerned have already urged on their members the need for conserving copper as far as they can. Some worthwhile results have already been achieved but I will always consider any proposals for speeding research in this field.
§ Mr. Harold Walkerasked the Minister of Technology if he will circularise all the industries for which he has responsibility urging them wherever possible to use suitable substitutes for copper or copper alloys, and to advise them of such 49W substitutes, namely, the use of nylon or other plastic tubing for the transmission of fluids.
§ Mr. BennNo. The resort to substitutes is best left to the commercial judgment of the users. But my Department's advice is naturally available to anyone requiring it.
