radiators need to dissapate heat, and metal can dissapate heat quickly
Radiators are made of a lot of metals with high melting points (example: Aluminum)
Silver is a valuable metal, and is thus not used in radiators.
Aluminum
aluminum and copper
car radiators used to be made of copper, copper doesnt rust. most radiators are now made from aluminum.aluminum also does no rust

Yes. Look for a metal recycling center or look up scrap metal in the phone book.. Depending on your location in the world, pricing varies. In the U.S. you can get upwards of $1.30 per lb for radiators. To see current pricing of scrap radiator and auto parts go to http://www.scrapmetalpricesandauctions.com
cars don't have plastic radiators, if they do the plastic would probably melt, and the compound of metal cools and heats quickly which is useful in cooling water.
