Brass, Bronze, and Copper Welding

Testimonials

Mike, I have to tell you that your 77 cast iron electrodes are fantastic--I need to order more to have it on hand.

 

I just welded a small block Chevy 400 engine with a broken ear on the starter mount. The engine was sitting on a 3 wheel engine stand and fell over breaking the mount. I placed a mild steel bolt in the broken mounting hole and built the whole corner back up, then I removed the bolt and re-tapped the bolt hole with no problem. It's looking pretty good.

 

I work on hard to find and restore irreplaceable antique cast iron parts. Your 77 welding rods are better than anything I've tried in the past. I'll try to remember to send you photos of my next cast iron job.

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.
