Abstract: A process is provided for efficiently and rapidly alloying a slowly soluble solute metal with a molten host metal maintained at a temperature of T.degree. C, the solute metal having a melting point of over T.degree. C + 100.degree. C. The alloying is effected without substantially superheating the molten host metal. This is achieved by forming a separate superheated hot melt of a master alloy of said solute metal with a portion of the host metal at a temperature in excess of T.degree. C + 100.degree. C and then blending said hot melt master alloy with said molten host metal to provide a predetermined final alloy composition of said host metal at an accelerated dissolution rate.

Abstract: A brazing alloy is provided consisting essentially by weight of about 30 to 50% copper, about 10 to 20% manganese, about 3 to 25% iron, about 0.5 to 4% silicon, about 0.5 to 2% boron and the balance essentially nickel.

Abstract: A brazing alloy composition is provided for brazing together a ferrous metal part to another part, said alloy comprising about 15% to 30% manganese, about 15% to 30% zinc, 0 to about 10% nickel (e.g. 0.5% to 10%) and the balance essentially copper ranging from about 45% to 65%, the brazed joint produced comprising a ferrous metal part on one side strongly bonded at the interface to another part.
