Dan, I would not worry about the hammering as when sheet is made it is rolled between hardened steel rolls.
Any hammer that has been use on an anvile has beenwork hardened anyway. If there is any contaminate it would be carbon or iron neither of which is harmful. Of cours you could buy sheet material as I did, but it is expensive. The better alternative is to buy #12 wire. "Ole Bob" -- The silver-list is a moderated forum for discussion of colloidal silver.
