Experimental results of nested cylindrical wire arrays (NCWA) consisting of brass (70% Cu and 30% Zn) wires on one array and Al (5056, 5% Mg) wires on the other array performed on the UNR Zebra generator at 1.0 MA current are compared and analyzed. Specifically, radiative properties of K-shell Al and Mg ions and L-shell Cu and Zn ions are compared as functions of the placements of the brass and Al wires on the inner and outer arrays. A full diagnostic set which included more than ten different beam-lines was implemented. Identical loads were fielded to allow the timing of time-gated pinhole and x-ray spectrometers to be shifted to get a more complete understanding of the evolution of plasma parameters over the x-ray pulse. The importance of the study of NCWAs with different wire materials is discussed.
