Brass and copper based alloys
This group includes four different categories of high-temp brazing alloys:
- General Purpose Brasses
- Brasses with addition of Nickel
- High temperature Copper Alloys for special applications
- Copper for furnace brazing
All these alloys are economical to use and can be generally supplied in a variety of forms (rods, wires, strips, preforms, powder and pastes). General purpose brasses can be used for brazing and for the Oxy-Fuel Gas Braze-Welding process, with liquid flux spread through the torch flame.

BRAZING ALLOYS FOR ARTISTIC PRODUCTION
The process for joining materials (also very small parts) used by artistic blacksmiths is brazing. Unlike other techniques, brazing doesn’t leave traces in final product and aesthetic aspect is not compromised.
