Brazing flux of stable suspension for aluminum material

摘要

A brazing flux for aluminum material having superior suspension stability whose melting composition of the flux is composed of four elements of MxAlFyOz (where: x=0.5 to 2.0, y=1.5 to 4.8 and z=0.1 to 1.0), and a method of producing a brazing flux in which an amorphous aluminum hydroxide is employed as an aluminum raw material to prepare the flux.
