Which category would include aluminum?

Explanation:
Aluminum belongs to non-ferrous metals because it does not contain iron. The key distinction is iron-containing materials (ferrous) versus those that do not contain iron (non-ferrous). Aluminum is not iron and is not magnetic like many ferrous metals, so it sits in the non-ferrous category. While aluminum is often used as an alloy (mixed with other elements), the defining category here is non-ferrous, not simply “alloys.” Precious metals are typically gold, silver, platinum, etc., and aluminum isn’t in that group, so the best fit is non-ferrous.
