The lower specific gravity saves the transportation industry money by reducing the weight of vehicles, ships, aircraft, etc.
Resistant to atmospheric effects (maintenance costs are reduced because aluminum products do not rust).
Excellent electrical conductivity (aluminum and its alloys are the only materials that can be used to transmit high-voltage electricity).
Specific mechanical properties contribute to relatively good formability.
It poses no health hazard.
It can be reused through recycling.
long lasting.
