Crossword Genius

Metal conductor (4)

Ross

I believe the answer is:

lead

I believe this clue is a double definition.

'metal' is the first definition.
(I know that lead is a type of metal)

'conductor' is the second definition.
(I know that lead is a type of conducting wire)

(Other definitions for lead that I've seen before include "Metal; show the way" , "Sort of poisoning" , "Principal role in a play" , "Metal - van - go ahead" , "Guide,direct" .)

I've seen this clue in The Globe and Mail.
