I have access to a lot of copper that has been tin coated...Does anybody know if I should try to "buff" the tin coating off, or take it to the scrap as is? I wasn't sure what type of price difference I would see.
I also have nickel plated brass too...
Start by getting a price list to compare. I'd say it's not worth it but some people don't mind going to a lot of trouble.
Tin coated copper goes for #2...only way to remove it is to burn it off
I took a good size batch of it in and they said the same thing, #2.
It is 99% pure tin over the copper. I was worried about not getting a very good price if they suspected it wasn't copper. I'm not worried about recovering the tin - as I am not sure how. Each piece of copper can be between 20 & 50 pounds, then it is coated with the tin, so I see good weight in copper, but I wasn't really sure about the tin part - leave it on or buff it out. If there is a way to recover it, that would be awesome, but I'm not sure how to do that.
@fatboy2131 Tin is only worth 12 CENTS /lb on LME its not worth trying to recover it.
Tin is $12.00 a pound. I think you are getting mixed up with steel for .12 a pound. Someplaces call steel tinQuote:

I sure know my food cans ("tin cans") aren't worth $12/lb.
Steel and tin are used interchangeably. I don't think anything is actually made using tin. Things are plated with it though.
Tin (the element) is used as a coating to prevent corrosion. It is never used as a separately. Commonly used in solder and to coat food containers (ie: tin cans).
