All LIFAN Power USA Pro and Platinum Series Generators come with Solid Copper Windings

The performance difference between copper and aluminum coil windings lie in the physical and resistance properties between the two materials. Copper is a more efficient conductor, able to transmit the same current with less cross section area to do the same job. Aluminum has a lower mass than copper and the aluminum wire, with its larger cross section area, is not as efficient as copper. Well-designed enclosures usually give better performance with copper windings in both quality and output than aluminum. This means it takes more power to reach optimal efficiency with aluminum.
