Minimal working around one uni then another for Al (9)
I believe the answer is:

(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for aluminium that I've seen before include "Lightweight metal" , "Al" , "Metallic element found in bauxite" , "Light metal" , "Silvery metallic element" .)
