Abstract

Fluxes for aluminium brazing or welding may be produced by grinding the slag by-product of aluminium boron master alloy production. The grinding is preferably to below 75 microns size but particularly preferably to below 30 microns size. The fluxes may be mixed into water to produce a stable, mobile slurry which may be spray-applied to an aluminium work-piece.
