The characteristics of wire and copper wire
(1) hard wire, soft copper wire(2) copper wire is better than iron wire
Chemical ways: Iron active stronger than copper, iron can dissolve in acid, copper can not. There are other heat transfer rate, obvious iron copper and high ductility, iron, copper is better.
Don't know what is the reason you asked this question, the differences between the iron and copper in many aspects, from the classification point of view, you should solve physics class of problems. It may be useful to you different resistivity parameter is iron and copper, iron and copper with high resistivity;
