Question 1

What is the melting or working temperature of this 54 Ag alloy vs the 45% ?

Accepted Answer

Thanks for the question!  56% Ag:  Liquidus  1145 F.  45% Ag: Liquidus: 1225 F. So the 56% alloy might be better if you want to limit the amount of time heating the assembly or if you want to expose the assembly to less heat. Another point: the 45% alloy requires a little more brazing technique than the 56% does since the 56% alloy flows quicker. With both rods, the flux coating makes the job much easier. If we can help in any way, please let us know.

Question 2

Do I need to use flux with these rods?, if so what type

Accepted Answer

The flux is in the orange coating! Our process delivers the right amount of flux in most cases. If the material to be brazed is oxidized or dirty, you may need more flux (or just a cleaning with a metal brush). But we think that you won't require more. The flux melts and flows around the joint just before the filler metal melts.  If you have further questions, let us know!

Question 3

How would these do on 20 gauge sheetmetal stress cracks ?

Accepted Answer

This item did not work for me for what I was doing. I was trying to brace copper to Stainless Steel. Do not know how it will work with 20ga sheetmetal

Question 4

Can I use a common butane torch with these brazing rods?  Or do I need an acetylene torch?

Accepted Answer

I wish folks would stop lying about map gas being hot enough to melt brazing rods like this. Any copper, nickel silver, type rods will not melt with just map gas. It does not matter the torch either. You need oxy fuel setup in order to braze anything other than aluminum. Seriously irritates me as I was led down the wrong path so many times, wasting 100's of dollars in the process and feeling like a fool for listening!
