Copper Brazing Alloys

Brazing of steel, stainless steel, nickel and copper/nickel alloys

Resistance against corrosion and ductility make copper brazing alloys attractive for many applications. Electrical and thermal conductivity as well as wetting characteristics are excellent.

Copper brazing alloys with high purity are brazed under vacuum. Inert gas atmosphere or brazing in air is also possible.

Phosphorous Copper brazing alloys are used to reduce copper; they behave like flux.

Brazing with zinc containing copper brazing alloys leads to high-strength joints. Overheating must be avoided due to the vapor pressure of zinc.

Copper brazing alloys are also available for high temperature applications.
