Myths about Aluminium Brazing Fluxes – Part 1

Aug 18
2016

Myth – Fluxes With a Lower Melting Range are Superior There are claims that a lower melting point flux is better for brazing (i.e. melting between 550 and 560°C – approximately 10 – 15°C below conventional fluxes). The idea here is to try to fool the engineer by illustrating the merits of “early” flux melting,

Selecting the Correct Flux –WHAT? The first requirement of an Aluminium brazing is to be chemically effective. Fluxes are categorized as active (corrosive) and inert (noncorrosive). Fluoride base fluxes → NON‐CORROSIVE The fluxes leave the white gritty residue on the part. These fluxes include the higher temperature potassium aluminium fluoride and the lower activated cesium

Aluminium joining – Brazing ‐ Flux function What is brazing? Brazing is the joining of metals using a molten filler metal. On melting, the filler metal spreads between the closely fitted surfaces, forms a fillet around the joint and on cooling forms a metallurgical bond. By technical definition ‘brazing’ is a joining process in which the filler metal
