I have 2 trash cans full of heating elements that have been removed from stoves & dishwashers. I understand they are made of nickel alloy. My question is do you sell them as is or do you break them down ( Don't know if Im suppose to remove the white powder and outer shell)? I hope the yards buy them as is ,seems like it would be alot of work just to get the nickel wire out. Any information is greatly appreciated. Thanks.......
