Aluminium - Wikipedia

Aluminium is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation. Aluminium and its alloys are vital to the aerospace industry and important in transportation and building industries, such as building facades and window frames. The oxides and sulfates are the most useful compounds of aluminium.

Copper and electricity. Resistance and resisitivty.

When we say that copper is a heavier metal than aluminium, we are comparing their densities. In a similar way, when we say that copper is a better conductor than aluminium, we are comparing their resistivities.. Density and resistivity are both bulk properties of a material. Their value doesn't depend on the size or shape of a particular sample – only on the material itself.

Cables: Materials Properties

The actual values of and depend both upon the materials chosen for the cables, and the sizes and shapes of the conductors. In general, larger cables tend to have a greater cross section of metal, and a wider dielectric gap, and hence can have lower loss, but this rule can easily be broken if one cable is manufactured with more care than another.

Superconductivity | physics | Britannica.com

Superconductivity: Superconductivity, complete disappearance of electrical resistance in various solids when they are cooled below a characteristic temperature. This temperature, called the transition temperature, varies for different materials but generally is below 20 K (−253 °C). The use of superconductors in
