Two copper-based alloys are proposed for use in electrical wiring operating at 600K. Alloy A contains 3% (by atom) zinc substituting for copper atoms, whereas Alloy B contains 0.5% (by atom) boron atoms occupying interstitial sites. Which alloy is expected to exhibit the higher electrical conductivity under these conditions? Justify your answer in terms of the atomic-level structure of the alloys.
