Abstract

1342726 Super-conductors PLESSEY CO Ltd 19 April 1971 [4 Feb 1970] 5239/70 Headings H1A A5 and A4D An electrical conductor comprises Nb, Sn and Cu with a minor amount of one or more of Al, Hf, Ti, V, Zr and has a region exhibiting superconductive properties which is formed from all the metals in the conductor. The conductor may also contain up to 20,000 p.p.m. oxygen and may be made by powder metallurgy or by plating a Nb strip containing the additive metal with Sn and Cn (e.g. by hot dipping plasma spraying or electroplating) and then heat-treating. The product is preferably provided with a reinforcing substrate (e.g. of stainless steel). Reference is also made to anodizing to provide the required oxygen content.
