What material do you use to fill in when sautering copper to brass? Is it brazing rod? silver sauter? etc.

Any input is much appreciated.

Thanks!

Unless you need the extra strength for high pressure or something, ordinary lead/tin solder should do. It sticks to both brass and copper fine if you clean it up good first. A/C lines must be silvered soldered because of the pressure. Using brazing rod would be tricky to avoid melting the brass you are working with.

Hi Mindy,

"What material do you use to fill in when sautering copper to brass? Is it brazing rod? silver sauter? etc."

In plumbing we use wire solder and a acid based flux called No-Corode. We first shine the two pieces with plumbers sandcloth. We then paint the surfaces to be soldered with a acid based flux. Then we apply heat to the largest fitting untill the solder starts to melt. We then run the wire solder around the two joints where it is pulled in by capillary action. When the joint will accept no more solder we let it cool and set up. Is this what you wished to know? Tom
