Aluminum is less conductive than copper, and as a result, aluminum wound transformers need to be designed using larger wire sizes. Larger wire translates to larger diameter coils and greater volume cores. This means an aluminum wound transformer will be bigger than a comparably performing copper wound transformer.

Aug 11, 2020 · Aluminum windings usually take up a larger cross-sectional area of dry type transformers than copper options. The more expansive design of the aluminum windings produces a lower current density, resulting in a lower rate of heat loss and saving more energy when compared to older-model copper wound transformers.
