Brass, Bronze, and Copper Welding



These pics come from a new aerospace test facility that they are constructing at the University of Notre Dame. The SSF-6 is working great.

I am attempting to make all of these fittings air tight as they are used for pressure measurements. We can¹t have any leaks. I had very little warpage of my base metal and I think this is really going to work out very well.

Copper Brass and Bronze

While copper, brass, and bronze may not be applications that are used every day in welding, industries such as refrigeration, electronics and plumbing—as well as ornamental artists, encounter these metals and perform brass, bronze, or copper welding jobs daily.


Here are some things to remember when working on brass, bronze, or copper:

Brass melts at around 1652-1724º F range and is fairly easy to cast. During any brass welding job, use high quality filler if the color doesn’t have to match the metal. Because of its relatively high melting point, low zinc brass can be braze-welded.


Super Alloy 1, SSF-6, and SSQ-6

Our Super Alloy 1 can bond all of these metals in any combination, and can be used in bonding with other metals such as aluminum—at 350º F.


Our SSF-6 Silver Solder is 56% silver and is especially useful when high strength is needed, or when you need high flow to get to those hard to reach areas.


Our SSQ-6 Silver Solder Paste is the same formula as our SSF-6, in a convenient 1 oz syringe.
