Title: Higher Melting Point Solder?
Post by: ROBOT on March 05, 2016, 11:21:12 pm
Anyone know where I can find some high melting point solder? I need it to be higher temp then the typical lead free.

Lead free plumbing solder melts at 450-460F
95% Tin and 5% Antimony.

That's extremely low.. I'm looking for something above 270C

How about some Sn05Pb95 (5% Tin, 95% Lead)?  301-314C melt range.

Eventually you will get up into brazing alloy range. Typically you need a torch for them but I have seen some that flow at dull red heat. They are very common in auto body repair.

Here is some multicore HMP series (SN5/PB93.5/AG1.5), and melts around 296-301C:

Straight lead.

Be wary with any solution: what you are soldering to will alloy with your solder.  This may have a lower melting point.  If possible, go for crimps.

 don't know if you are still looking for higher melting point solder but you can score 1lb rolls of Kester 44(RA) or 285(RMA) Sn10Pb88Ag02 for quite cheaply, the Melting Range  is 514-570°F / 268-299°C

What is your target melting point?

Felder in Germany will mix solder for custom specifications
