Threw around titanium corrugation (7)

Ross

I believe the answer is:

fluting

'corrugation' is the definition.
(thesaurus)

'threw around titanium' is the wordplay.
'threw' becomes 'flung' (flinging is a kind of throwing).
'around' is an insertion indicator.
'titanium' becomes 'Ti' (Ti is the chemical symbol for titanium).
'flung' enclosing 'ti' is 'FLUTING'.

I've seen this clue in the Sydney Morning Herald.
