solder types and temperatures

[bellssuperlube]

I am looking for a solder that can withstand 385 degrees F. without turning to liquid. Does anyone know what type of solder I could use that has a higher melting point but still flows easily?

Welcome to the fray.

What's the application?

100% tin melts at 449 deg. F, 96/4 tin/silver melts at 430 deg. F.

Is brazing out of the question?

Let us know what you want to do; we'll try to help.

Be well.

HankJ,

I am soldering small brass tubes. I can easily buff away any excess solder to keep the appearance pleasing to the eye. I don't know if I would be able to braze the tubes and still make it look good. I have used solder in the past with good results but I am going to get this powder coated when finished and the normal solder will not withstand the baking. You mentioned something about pure tin and a 96/4. Do these have a special name, could I get them at a welding store? Sorry for my ignorance and thank you for your help.

No need to apologize to anyone on this forum. That's why it's here!

You should be able to find either one or both at your neighborhood hardware store. When I worked for ACE, we carried 'em.

Be well.

When I was doing some gunsmithing we used silver solder for higher strength applications. If I remember correctly, melting is somewhere around 1100 to 1200 deg F. The higher the silver content, the harder and higher the melting point. We used an acetylene torch (with the air mixer, not oxygen and is easy to work with. Silver solder is easy to find. Almost any electronics store, Radio Shack, or silver smith/jewlery maker should have it. Will also need the paste flux to go with it. Also it's not very expensive.
