FLUXES FOR BRAZING AND BRAZE WELDING

LOWFLUX

During brazing, the base metal of the joint must be wetted by the molten liquid metal (filler metal).

The brazing of the joint is obtained only if both metals, liquid and solid, are free of surface oxides that would otherwise impede their contact: both existing oxides and any generated during heating.

The consistency of the oxide at room temperature varies according to the metal type. This requires choosing the flux carefully and taking into account the base material and the working temperature of the alloy.

SALDFLUX fluxes are boric acid-free and manufactured in compliance with REACH standards.

The low-temperature LOWFLUX® fluxes are used with alloys having a high silver content (starting from TERNALLOY 55) and a low melting temperature. They are recommended for small precision brazing or when alloys with very fine diameters (<<0.9 mm) are used. It enhances the capillarity and smoothness of the alloys and guarantees a joint surface that is free from impurities or oxidation residues.

BRASFLUX

The deoxidants of the type BRASFLUX® are of universal use for every type of application to be combined with any alloy with a range of fusion of less than 800 C .

They have a wide range of activities, excellent oxides reduction and coverage during brazing (both manual and induction).

The choice of the correct deoxidant is one of the determining aspects to obtain a good result. therefore it must be done very carefully according to the type of alloy chosen and the type of heating used.

UTENFLUX

The line UTENFLUX® includes disosisiants to be used in all extreme situations, either for brazing times or for the use of high melting alloys. Very suitable for brazing refractory steels, stainless steels, when the wettability of the alloy used is a critical.

In particular, the UTENFLUX F9®deoxidant, with its characteristic brown colour, is very common in tool brazing with widia or PCD inserts.

FLUX - TETRAFLUX

The deoxidants of the line TETRAFLUX® are used only with brass alloys type WELD®.

They have a different composition than traditional deoxidants, because they must have a very high working temperature.

They are available both in powder and paste and also in the liquid version, but in this case they need a special system for its use.
