The fact of the matter is that aluminum wiring is a waste, but using aluminum cables proves to be a very good idea. Aluminum is lighter than copper. Aluminum has a resistivity varying from 2.65 to 2.82 × 10 −8 Ωm. Combined with it's light weight and alloyed with some other metals to make it stronger, aluminum is ideal for electrical cables.

Aluminum is a very light metal, wear-resistant, ductile, conducts electricity and heat well, and has no magnetic properties. Aluminum has a light silvery color and is covered with a thin oxide film on top. It is this film that is the main source of aluminum corrosion protection. The oxide film has self-healing properties and is very durable.

To resistance spot weld aluminum with steel, a sheet of aluminum-clad steel can be used as the transition material between the two (Haynes and Jha, 1999). As the weld current is applied, the higher resistance of the steel–steel interface causes the steel side to heat up rapidly while the aluminum–aluminum side acts as the heat sink.
Thermal resistance is the temperature difference, at steady state, between two defined surfaces of a material or construction that induces a unit heat flow rate through a unit area, K⋅m2/W. According to this definition and Equation 1, Equation 2, therefore, can be obtained.

between two bodies, 1 and 2 (unless all the heat flowing through frontier-1 also flows through frontier-2). The First Law applied to a regular interface (a non-dissipating one) implies that the heat loss by a system must pass integrally to another system, and the Second Law means that the hotter system gives off heat while the colder one takes it.
