Morphology

cast-iron = cast + iron (semi-transparent) = cast + iron

The components are literal (iron that has been cast), but the adjectival meaning 'extremely strong/firm' is a metaphorical extension beyond the material sense.

Etymology

The word cast-iron comes from the metal cast iron, which is made by pouring hot iron into a mold and cast means 'to pour'. So to call something cast-iron is to say it is very strong or certain, like an object made from that hard metal.
