Copper, Brass, and Bronze Brazing and Soldering Processes

While copper, brass, and bronze may not be applications that industries such as refrigeration, electronics, and plumbing (as well as ornamental artists) use every day in welding, many do encounter these metals and perform copper, brass, and bronze brazing and soldering processes daily.

Here are some things to remember when welding copper, brass, or bronze to steel:

Brazing brass to stainless steel is a fairly easy process. 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 can bond all of these metals in any combination and can be used in bonding with other metals such as aluminum—at 350º F.

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.

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