Aluminium Alloy General Information Introduction to
Electrical and Thermal Conductivity. Aluminium is an excellent conductor of both heat and electricity. The great advantage of aluminium is that by weight, the conductivity of aluminium is around twice that of copper. This means that aluminium is now the most commonly used material in large power transmission lines. The best alternatives to copper are aluminium alloys in the 1000 or 6000 series
