Abstract

A method of brazing aluminum parts where the brazing occurs between one aluminum part and a second part formed of either aluminum or another metal, wherein the aluminum or aluminum alloy has a braze cladding which is plated with a bond-promoting alloy prior to the brazing operation. If an aluminum brazing foil is utilized between the parts, the bond-promoting metal is plated onto the brazing foil. The bond-promoting alloy includes nickel or cobalt with a small amount of lead added thereto, such that the nickel-lead or cobalt-lead may be used individually or in combination.
