The SOUBRAZ range of soldering fluxes and flux removers is specially designed to optimize your brazing, soldering and activated soldering operations. Our formulations ensure perfect surface preparation, effective protection against oxidation, and optimum wettability to guarantee strong, clean and long-lasting solder joints.
Available in paste, liquid, gel or powder form, our fluxes cover all types of metal (copper, brass, steel, stainless steel, aluminum) and brazing processes (flame, induction, furnace, salt bath, etc.).
What is a flux or flux remover?
A flux (or stripper) is an active chemical substance applied to surfaces before or during brazing. It :
- Cleans metal oxides from surfaces.
- Protects against reoxidation during heating.
- Promotes filler metal spread and adhesion.
A good flux ensures a homogeneous metallurgical bond, without inclusions, porosity or harmful residues.
