.... Of the three types of cast irons, malleable iron is generally considered to be the most brazeable, and gray iron, characterized by large flakes of graphite, the most difficult to braze. Until the development of electrolytic salt-bath cleaning, brazing of gray iron was considered impractical. Ductile iron has...
