Regardless, aluminum is expensive to extract and refine, requiring a tremendous amount of energy. In terms of cost, on average aluminum is more expensive than steel.

The BWW i3 uses an Aluminium frame exactly because it reduces weight. https://www.marklines.com/en/report_all/Munro003_201710 https://www.marklines.com/en/report_all/Munro003_201710
