brass and copper alloys

Brazing brass and copper alloys

Cheap alloys for general utilization with a higher melting temperature than silver alloys. They are used to join iron, steel, copper and its alloys, nickel and its alloys. This alloys can be use either for brazing or soldering, with liquid flux provided by the flame of the torch from a special vaporizer.

Copper is mainly used in rings format or preformed for oven brazing in protect atmosphere. They are available in in different formats: rods, wires, foils, preformed, powder and pastes.

BRAZING BRASSES

Alloy generally applied on steel, nickel and their alloys. They can be used with all brazing processes including flame, provided they are slightly reducing.
Not suitable for furnace brazing in a controlled atmosphere.
We recommend avoiding strong overheating during the brazing procedure in order to avoid zinc evaporation.

Alloy generally applied on steel, nickel and their alloys with addition of tin to increase fluidity properties. They can be used with all brazing processes including flame, provided they are slightly reducing. Not suitable for furnace brazing in a controlled atmosphere.
We recommend avoiding strong overheating during the brazing procedure in order to avoid zinc evaporation.
Alloy often used with liquid flux dosed directly on the torch flame through the appropriate vaporizer.
Used as filler or for reconstructing gear teeth, bearings, shafts, valve seats, steering joints, handlebars and bicycle frames, metal furniture, pipes, etc.

-

Copper based alloy with high-melting point. It is suitable to join steel, stainless steel, nickel and nickel alloys. Being zinc-free, and because of its high brazing temperature, it is usually used only in protective atmosphere protecting brazing. Its typical application are in the field of carbide and diamond tools.
