%X Near-constant electrical resistivity over 4.2 to 360 K in a pseudo-B2 Al2.08CoCrFeNi is reported. Absolute values of coefficients in electrical resistivity equation as a function of temperature, ¦Ñ(T) = ¦Ñ0 + Aln(T) + BT2 + CT3 + DT, decrease as temperature rises, manifesting that they gradually become less while temperature increases. Overall average temperature coefficient of resistivity (TCR) in 4.2 to 360 K is 72 ppm/K, with a half-parabolic shape in its resistivity-temperature curve that is similar to Manganin. It shows that the phonon effect on this alloy keeps nearly the same through this temperature range.
