Metthiessen's Rule (M.R.) and empirical relations between resistance ratio (R=ρ300/ρ77) and resistivity (ρ77) of Al-Fe and Al-Si binary alloys containing total other impurities less than 0.1% were investigated. Relations corrected for binary solid solutions having deviation from the M.R. were proposed. To avoid systematic positive error of geometrical size factor, size fac-tor was determined by density method. Though there remains a possibility of correction in future because of effects of the other impurities, the empirical relations for the Al-Fe dilute alloys, 2.5<ρ77/nΩ•m=24.767/(R-1)+0.0574<3.5and for Al-0.37-1.35%Si alloys, 5<ρ77/nΩ•m=25.854/(R-1)-0.1487<11were temporarily recommended. Gradient of ρ77 vs. (R-1)-1 plot for the Al-Fe alloy was smaller, and that for the Al-Si alloy was larger than ideal value, suggesting "negative" and "positive" deviation from the M.R., respectively. On the comparison of these relations, the previous relation reported for the commercially pure aluminium coincided to those of binary alloys within 1% accuracy.
