I think it's a little harder to work with than lfb, but probably just because I only use it on stainless and stainless hates to be heated to nickel silvers melting point.

We used it at trek because it has silver in the name, although that's a misnomer because it contains no silver. It got the name because it's silver. Seems like the Chinese call it "white copper" which is probably better name for it.
