Abstract
A brazing product for fluxless brazing comprises a substrate and a filler metal-forming composition applied to the substrate. The substrate preferably comprises aluminum, an aluminum alloy or another metal and may include at least one layer of a ceramic, carbide or nitride. The filler metal-forming composition comprises a liquid-forming layer comprising silicon and a braze-promoting layer comprising one or more metals selected from the group comprising nickel, cobalt, palladium and iron. The liquid-forming layer comprises one or more material layers. Where the liquid-forming layer comprises a plurality of layers, it may include at least one layer consisting essentially of silicon.
