I bought 10 of these rolls of Lead Free Solder five or six years ago and haven't hardly touched them since.

Getting ready to now and I see that nowhere do they say what their composition is.

The wire is about an eigth of an inch in diameter and solid, no flux. They're soft, but not nearly as soft as lead solder. I cast some into my Lyman ingot moulds and they stay liquid in the cold mould far longer than lead alloys.

Thanks.

Lead free solder is 95 - 98% tin depending on the maker. Close enough to pure for our purposes.

Thanks ima. I thought that that was the case but wasn't sure.

Since I paid a dollar a pound I guess I shoulda bought a hundred of 'em. Isn't hind sight wonderful?

It is a high tin alloy that Kester named 'Aquabond'.
This is the MSDS ...

If you had purchased $500 worth of that solder it would have contained $450 worth (14 troy ounces) of silver ! :) :)

More important. It is worth 10 times what you paid for it, back then!
