As copper, for example, call time after disturbance (8)

I believe the answer is:

metallic

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

'as copper for example' is the definition.
I can't judge whether this definition defines the answer.

'call time after disturbance' is the wordplay.
'after' says to put letters next to each other.
'disturbance' indicates anagramming the letters.
'call'+'time'='calltime'
'calltime' with letters rearranged gives 'METALLIC'.

Can you help me to learn more?

(Other definitions for metallic that I've seen before include "Characteristic of a shiny solid element" , "like 28 [SILVER]" , "Like iron, gold, etc" , "Relating to a lustrous elementary substance" , "Call time (anag.)" .)
