I like to sell scrap copper wire, copper pipe,aluminum, bronze and steel?

It doesn't sound as if you actually want to create an ongoing business concern, where you'd be buying and selling scrap. Call around to local / regional scrap metal companies for the best "bid" price for each of the metals (let them know how much you've got, you may get a better price) and sell the metal to them. You would just be their customer, so you would not need any kind of permit.
