The history of aluminium industry
Humankind came across aluminium long before the metal we know today was produced. The Natural History by Pliny the Elder, a Roman scientist, told the story of a first century craftsman presenting a cup made of an unknown metal looking like silver, but too light to be sliver, to Tiberius, the Roman Emperor. Alum, an aluminium-based salt, was used extensively in ancient times.

metal Why is copper a better conductor than iron
Copper is a simple noble metal with a beautiful near-ideal Fermi surface (see Ashcroft and Mermin's Solid State Physics book, or C.Y. Fong et al., Comparison of band structures and charge distributions of copper and silver). It turns out that the Fermi surface of copper is almost exactly what one would expect from the free electron sphere.

The anodic metal will corrode in preference to the more passive metal, which becomes cathodic. An example of this is the coupling of copper to steel in the HVAC piping in the barracks. The steel, being more active (less noble), becomes anodic to the copper, which is more passive, and becomes cathodic.
