| Laboratory 2 X 3176 Conductivity Tests of Aluminium Alloys Method of Test 31st Aug 1917 Re. Conductivity Tests in Aluminium alloys The method employed was intended to show the relative conductivity values under piston conditions. Bars 18" long shaped as rough steeld billets were cast under piston conditions. Two or three bars were heated up to the point C in an electric furnace. A & B represent the position of fusible alloy tablets outside furnace & screened from its heat & also from outside air currents by a hood. Relative conductivities were obtained by the time taken for alloys at A & B to melt when furnace was kept at 500°C. Two or three bars could be done simultaneously. | ||
