The project is for a course entitled: Science of Materials. So I am mostly interested in the different materials used to make a refrigerator (ex: steel, foam, ...) and why did engineers opt for one material not the other (ex: lower cost, more resistant to temperature...etc).
The refrigerator i'm interested in is a home refrigerator in general (ie the refrigeration and the cabinet).

If you can help or redirect me to a site that can, I would apperciate it enourmously,
thanx,
ayah
