Aluminum wire is a wire used for electrical wiring in houses, power grids, and airplanes. Aluminum wire is an alternative conducting material considering its electrical and mechanical properties and price linked to copper wire. Aluminum is poorer electrical wiring compared to copper, so it is infrequently used in small applications such as home wiring.

Like Copper wiring, aluminum has many applications – however, it also has several differences thereto to copper. Electrical utilities use aluminum wiring for transmission lines.
