The thermal properties (heat capacity, thermal diffusivity, and electrical
resistivity) of a Cu + 10 wt % Sn alloy in both solid and liquid phases hav
e been reported. Using these values it was confirmed that the Lorenz relati
on is suitable for obtaining thermal conductivity from electrical resistivi
ty in the liquid phase of this alloy. Also, the temperature differential (d
lambda/dT) obtained from such an approach was in excellent agreement with
the thermal conductivity values calculated from thermal diffusivity.
