Abstract
A brazing product for low temperature fluxless brazing comprises a filler metal-forming composition which melts in the range from about 380-575.degree. C. The filler metal-forming composition comprises zinc optionally in combination with aluminum and/or silicon, and further comprises at least one braze promoter selected from nickel, cobalt, iron and palladium. The filler metal-forming composition may comprise a single layer or may comprise a number of distinct layers. The brazing product may take the form of a brazing preform or a brazing sheet or casting in which the filler metal-forming composition is deposited on a non-consumable substrate. The substrate may preferably comprise aluminum or an aluminum alloy, but may instead be comprised of one or more metals other than aluminum.
