Abstract. Measurements of the coefficients of thermal conductivity and electrical resistivity are reported for a chromium-copper alloy (`Hidurel 6') to 400°C. An absolute steady-state radial heat flow method was used for the thermal conductivity determinations and a relative resistance method for the electrical conductivity measurements.

The coefficient of thermal conductivity over the range 0-400°C could be correlated by k_`H6' = (3.42 + 6t × 10^-4) W cm^-1 degC^-1 where t is in °C. The temperature coefficient of resistance was 3.52 × 10^-3 degC^-1 and the coefficients of electrical resistivity, ρ_t (ohm cm, t in °C) for 20°C and 200°C are ρ₂₀ = 1.987 × 10^-6 ohm cm, and ρ₂₀₀ = 3.25₈ × 10^-6 ohm cm.

The validity of the thermal conductivity observations was shown by the very good agreement with the Smith-Palmer (1935) correlation.
