Re: [Harp-L] Re: Phosphor bronze and silver solder
Tin, lead silver content in that order, 62% tin, 36% lead, 2% silver.
Personally I wouldn't use a rosin core solder because you'll have less
control over what fluxes. I'm not sure why you're bothering with the
solver at all if you still get 36% lead. The silver makes it stronger.
You don't care how mechanically strong the solder is for your
application. It would lower the melting temperature if you didn't have
all that lead. You can get a low temp non lead bearing solder but it
will be expensive. Praxair used to carry a product called Mig 30 or Mig
20 but I haven't seen it there lately. It's very strong, very low temp
and doesn't have any lead in it. I don't like lead solders but not for
health reasons. I don't like how they flow and it's what you get used
to. If you're worried about annealing the brass reed use a thin piece
of paper under the reed. It's enough of a heat sink to give you a wider
margin of error. You'd have to get the reed to colour to anneal it,
that's more heat than you would think it is. ymmv, fjm
