This term describes something that does not involve or is not made of aluminum.
The nonaluminum materials used in the construction are more environmentally friendly.
Nonaluminum → It is formed from "non-" (meaning not) and "aluminum" (from Latin *alumen*, meaning bitter salt or alum). The word "nonaluminum" means not aluminum, indicating the absence of aluminum in a substance.
Think of 'non-' meaning not, so nonaluminum refers to something that is not aluminum.
