Oxidation has few practical implications apart from the corrosion that can happen at connection websites due to it.
Electricity is transmitted from the utility generating stations to particular person meters using almost completely aluminum wiring. In the united states, utilities have used aluminum wire for over one hundred years.

Reported issues with aluminum wiring have been related to the overheating and failure of aluminum wiring terminations. This is due to the tendency of aluminum wiring to oxidize, and aluminum’s incompatibility with units designed for use with copper wiring solely. Aluminum has a better rate of enlargement than copper wiring, which can result in free connections, arcing and melting, finally fire. Warm cowl plates or discolouration of switches or receptacles, flickering lights or the scent of hot plastic insulation may be evidence of poor or improperly made connections.
Loose connections improve electrical resistance, which can melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds should be used.
