Morphology

nonferrous = ferrous (transparent) = non + ferrous

The adjective is a straightforward negation: 'non-' + 'ferrous' = 'not containing iron'; the morphological relation is direct even if 'ferrous' is somewhat technical.

Etymology

Nonferrous comes from non- 'not' and ferrous 'iron', so it describes metals like copper and aluminum that do not contain iron and therefore do not rust like steel.
