To give a better appearance to your joint work and ensure their solidity, do not hesitate to resort to brazing. For this, the use of flux is indispensable. Available in different forms (liquid, solid, paste, and gas), brazing flux is a fusion of chemicals that ensures good dilution of the filler metal on the objects to be assembled.
Brazing flux is an important element in brazing. Indeed, it eliminates any trace of oxide present on the objects to be assembled, protects the objects from oxidation during brazing, and finally, reduces the basic tension of the filler metal. Flux comes in different models for specific uses. Thus, if you are going to work on aluminum, it is better to choose the corresponding brazing flux rather than another one to ensure the quality and finish of your work. You will also find brazing fluxes designed for zinc and stainless steel, and brazing fluxes for silver... The quality of the brazing greatly depends on the flux. Indeed, if the application of the flux is insufficient, the brazing will be fragile. However, too much flux will not have much impact on the brazing.
