Abstract

788,713. Preventing corrosion. REYNOLDS METALS CO. June 25, 1956, No. 19674/56. Class 123(1) In the cathodic protection of buried or submerged metallic structures, for example a pipe 1 buried in soil 2, the anode 3, which is connected to the pipe by a conductor 5, is cast from an alloy of aluminium and mercury, the preferred proportion of the latter being from 0.01 to 10 per cent by weight of the alloy.
