Brazing Powders and Pastes

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
- Electrolytic Copper

All these alloys are economical to use and can generally be 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.
