The aqueous solutions of zinc chloride, ammonium chloride, hydrochloric acid, triethanolamine hydrochloride, hydroxylamine hydrochloride and hydrazine hydrochloride may be used as fluxes in mechanised brazing of copper or brass components using low melting brazing alloys. Ammonium chloride, hydrochloric acid, and hydroxylamine hydrochloride should be used as fluxes for brazing of copper. All the investigated chemical compounds improve the technological properties effluxes, containing 10-25 percent of zinc chloride. The results of the investigations can be used for sys-tematising the chemical compounds used as fluxes for the mechanised brazing of copper and its alloys.
