Metal, it’s brought up North (3)

Ross

I believe the answer is:

tin

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

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

'it's brought up north' is the wordplay.
'it's' becomes 'it' (I can't justify this - if you can you should give a lot more credence to this answer).
'brought up' is a reversal indicator (in a down clue, letters go up).
'north' becomes 'N' (abbreviation).
'it' backwards is 'ti'.
'ti'+'n'='TIN'

Can you help me to learn more?

(Other definitions for tin that I've seen before include "Silvery metallic element" , "Silvery-white metallic element" , "Silver-white metal, used to make cans" , "Atomic number 50" , "Element, symbol Sn" .)
