Copper Brazing with Silicon Bronze for Home Brewery

Hello all,

A friend of mine asked me to make him some workpieces out of copper for his home brewery. Ultimately I want to TIG braze the copper together with Silicon Bronze.

1) Is silicon bronze safe for this application? If not, what would you use?

2) When I've tried to braze with the sil bro, the filler rod just balls up as soon as I touch it to the workpiece.

Why not just tig weld the copper? I don't know much about copper so I'm just asking

You can braze copper with silicon bronze, get it really clean. I don't know what you are working with , but thin stuff is a real challenge.

clean the copper with vinegar and salt first then try using 14ga copper wire for your filler metal...
