brazing flux

Flux

Flux have the purpose to obtain a surface free from oxide to allow the brazing. A filler metal wet itself and flow on base metal only if both are free from oxide on the surface. Then flux have the property to guarantee the wettability removing the oxides that forming with high temperature. Saldobrase offers a complete range of flux, because each material have to be treated at its best.

FLUX

Non-corrosive flux for soldering copper, brass, bronze, steel, stainless steel, nickel and hard metals. It is used with silver alloys, copper-phosphorus or phosphorus-copper-silver alloys, when brazing copper with copper alloys (bronze or brass).

Powder/Paste

500-750

FH 10

The removal of any residue can be carried out either mechanically or by washing or pickling.

Flux supplied as white paste, corrosive, easy to dose, for brazing copper, brass, bronze, steel, nickel and its alloys. Excellent resistance to prolonged heating and high temperatures. It is used with silver alloys, copper-phosphorus or phosphorus-copper-silver alloys, when brazing copper with copper alloys (bronze or brass).

Paste

500-800

FH 10

The removal of any residue can be carried out either mechanically or by washing or pickling.

Flux supplied as white paste, corrosive, easy to dose, for brazing copper, brass, bronze, steel, nickel and its alloys. Suitable for brazing with automatic systems thanks to its formula which allows an optimal dosage.

Paste

500-750

FH 10

Stir well before using. The removal of any residue can be carried out either mechanically or by washing or pickling.

Flux recommended for brazing tungsten carbide intended for tools and steels. Its prolonged operating time makes it useful for applications which require slow and prolonged heating.

Brown paste

510-1000

FH 12

Stir well before using. The removal of any residue can be carried out either mechanically or by washing or pickling.

Flux in powder indicated for brass alloys which also contain elements such as nickel, silicon, tin and manganese. Specifically designed for high temperatures.
