Answer
Copper is a better conductor than aluminum because it has a higher conductivity and is able to better withstand load surges.
Copper has a higher tensile strength than aluminum, which allows it to resist stretching, nicks, and breaks, and prevents failures and interruptions.
The conductivity of a material depends on the number of free electrons and the drift velocity of electrons when an electric field is applied.
Aluminum is about 40% less conductive than copper.
