'aluminium-built' originates from English, specifically the compound of 'aluminium' and 'built'. 'Aluminium' originates from New Latin 'alumen', where 'alumen' meant 'bitter salt' and the suffix '-ium' was later used to form names of metals; 'built' is the past participle of 'build'.

'aluminium' was coined in the early 19th century (attributed to Humphry Davy) from Latin 'alumen' → New Latin 'aluminium'; 'build' comes from Old English 'byldan' (to construct) → Middle English 'bilden' → modern English 'build', with 'built' as its past participle. The compound 'aluminium-built' is a straightforward modern compounding of the metal name + past participle.

Initially 'alumen' referred to a 'bitter salt' used in dyeing and tanning; over time the term evolved into the metal name 'aluminium' which now denotes the element. 'Built' originally meant 'to construct' and has retained that core meaning; together the compound came to mean 'constructed of aluminium'.
