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
