[Amps] Transformer material weight

[Randy S.]

Question about transformers .. 
If I was to buy the laminates and wire to wind
a 2 KVA transformer and say it weighed 50 lbs.
What would be a good guess for how much of that
was iron and how much copper ..?? 
 
Side Note.. It seems my acct may have been hacked .. 
So I changed the password .. 
I apologize for any spam emails that were a result of that ..
