Public Answer

Generac is one of the few companies to offer premium aluminum enclosures on residential backup generators. Aluminum enclosures are naturally rust and corrosion-resistant which allows for a longer lifespan. For salt air or high humidity conditions, aluminum is highly recommended to ensure decades of worry-free service. 
 

If the enclosure is aluminum, why is a magnet still attracted to it?

The outside shell of the generator can be ordered as aluminum, but the inside structure is made of steel. If a strong enough magnet is used, it will be attracted to the steel inside of the generator's shell.
