Cast Resin Transformers L.V Winding

the advantage of aluminum foil is that i can buy it at the supermarket to keep my food warm

Hello Eng.alasad

I do trust this is not a Class or Homework Question, because those are against the Rules.

The comparisons are easy to do:

Copper_ Aluminium

Expensive____________________Cheap

Easy to weld_________________Difficult to weld

Withstands sudden overload____Melts

Heavy______________________Light

Reddish Brown_______________Silver Colour

Low Corrosion_______________High Corrosion

There are other comparisons, and if you think a bit about your own question, you should be able to come up with several more.

Kind Regards....
