reference source for copper conductivity vs. temperature
· The Bloch-Grüneisen Formula gives you a function of resistivity vs. temperature. Debye temperature Θ is a parameter of the function. Its value for pure Copper is Θ Cu = 343.5 K. If you can t find the value of the Debye temperature Θ alloy of your particular alloy you can make some measuremnts over the interesting temperature range and

Resistivity of CopperThe Physics Factbook
Like most metals as the temperature goes up so does the resistivity. Because of these factors copper is widely used for electrical purposes such as electrical wires electrical machinery and generators and is able to withstand the elements to be used in outdoor power lines.

Resistivity of CopperThe Physics Factbook
It is a transition metal on the periodic table (atomic number 29) with a reddish- brown color that is malleable and ductile. It resists corrosion and is a good conductor of heat and has a high conductivity when it comes to electricity. This is why the main uses of copper are electrical.

reference source for copper conductivity vs. temperature
· Data from NIST (table 2) At low temperatures the resistivity of copper approaches a "residual" resistivity. However this isn t really a concern until below 100K. At higher temperatures the resistivity is best approximated with a linear increase vs. temperature (as you ve already found).
