Abstract

THE copper-nickel alloy wire used for close-wound resistors in Naval instruments is an oxidized wire having 0.001 cm thick oxide which offers electrical insulation to a potential difference of about 15 volts. At present, the oxidized wire used by the Navy is of imported origin. A problem has, therefore, arisen to develop a process for producing the oxidized wire locally. Work was, therefore, taken in Naval Chemical and Metallurgical Laboratory, Bombay, to find the expe-rimental conditions to produce the oxidized layer with requisite electrical insulation characteristics.
