It's used in electroplating (3)

I believe the answer is:

tin

I'm a little stuck... Click here to teach me more about this clue!

'it's' is the definition.
I can't tell whether this defines the answer.

'in electroplating' is the wordplay.
'in' indicates a hidden word.
'TIN' can be found hidden inside 'electroplating'.

'used' is the link.

Can you help me to learn more?

(Other definitions for tin that I've seen before include "Earnings" , "A silvery-white metal, symbol Sn" , "Silvery-white metallic element" , "Silvery metallic element" , "roofing material" .)

I've seen this clue in the Evening Standard.
