Electrical conductivity of metals at high temperature

About 20 years ago, I developed a computer code for Los Alamos National Laboratory to model imploding liners: cylindrical shells driven inward with intense magnetic pressure to produce a strong on-axis shock. The model required continuous curves of electrical conductivity for metals over a broad temperature range — room temperature to ~100 million °K. The data may be useful to specialized researchers, so I am making it available here.

Conductivity in the low-temperature range is available in most handbooks and on the Internet. For the range to the melting point, I used data on exploding wires from the reference T. Tucker and R. Toth, EBWl:  A Computer Code for the Prediction of the Behavior of Electrical Circuits Containing Exploding Wire Elements (Sandia National Laboratory Report SAND-75-0041, 1975). The references G. Rinker, Phys. Rev. B 31, 4207–4219 (1985) and Phys. Rev. A 37, 1284–1297 (1988) give theoretical values for conductivity in dense plasmas. I could not find data for the intermediate regime from the explosion point to the low-temperature plasma state, so I constructed reasonable interpolations. Figure 1 illustrates the temperature regimes and the interpolated region for copper.
