| To O.{Mr Oldham} C. from EFC. EFC1/ATS.7.17. X.3039.- RE RESISTANCE WIRE FOR HEATING COILS FOR TENSILE TESTS OF ALUMINIUM ALLOYS. We should be glad if you will kindly address an enquiry to the Electricity Offices on London Road, as to the possibility of obtaining, from the makers of Electric Resistance Radiators, some wire of the same material as used for this purpose, which, we believe, is called Nichrome. In particular we require a length of wire suitable for a voltage of 200 which, when embedded in clay in the form of a fairly close coil about 2" mean diameter, will attain a temperature of about 900°C. We think that the length required would be about 10 ft. EFC. | ||
