When in contact with air for a long time, aluminum oxide will be produced. The resistance of the joints or welding parts will increase or even overheat and burn out. The performance of the aluminum wire motor will continue to deteriorate over time. Not only will its lifespan be greatly shortened, but it will also be more susceptible to oxidation after welding, causing early corrosion and falling off, resulting in poor contact, or increased resistance, which can easily cause heat and even fire.
