The red-brown brass known as Muntz Metal is a copper alloy of sixty percent copper and forty percent zinc with trace amounts of iron. It’s named after British manufacturer Edward Muntz, the developer of this combination. Muntz brass is extremely strong and must be worked hot. It’s very effective for castings, extrusions, and hot forming.
Welding, soldering, and brazing are the most commonly used methods of metal joining. It is critically important that users be aware of the risks of the fumes released when welding anything containing zinc. Proper precautions must be taken to assure all necessary access to fresh air for the safety of all involved.
