Crossword Genius

Iron alloy used for brace (5)

Ross

I believe the answer is:

steel

I believe this clue is a double definition.

'iron alloy' is the first definition.
(I've seen this before)

'brace' is the second definition.
(steeling is a kind of bracing)

'used for' acts as a link.

(Other definitions for steel that I've seen before include "Make hard and unfeeling" , "Hard, strong, grey alloy" , "Strength, determination" , "brace" , "The staying power" .)

I've seen this clue in The Telegraph.
