Separating Grades?

its hard to tell you how to seperate as many yards class things different.here in southern ohiothere are 2 aluminium prices.regular and aluminium wheels.now we need to seperate our cast from sheet but the price is the same.on the steel if your area is like mine anything as thick as a lawnmower deck pays better than the thin shred items.we call them shred/tin/appliance.anything that is thick enough and is no more than 2 feet wide by 4 feet long is called short iron,so i seperate that,any thing the same thickness but longer is long iron.in the recent years long iron often pays the same as shred so i always call to see the difference in price befor i seperate,or to decide if i want to cut the long down to short,also to be short or long iron grade it needs to be free of wood,plastic,aluminium or anything else.around here they wont mind a touch of aluminium or something thats really fused to something as long as its 98 percent clean.it will take you time to learn what your yard wants.i read in hear earlier someone telling you to bust those motor casings,thats what i do also .any cast iron will break fairly easy.also on our wire if it is shiny or bigger than a pencil lead we get number 1 if not number 2.and that means not varnished,painted,or coated.we just recently have been outlawed from burning the wire in my state.so our copper grading is in the process of changing drasticly.anyhow i hope this may help you a bit
