A composite metallurgical product includes a roll cast aluminum alloy core and a filler material bonded on the core. Assemblies joined by filler material are formed from this product by heating to flow the filler material into joints and subsequent solidification of the filler material in the joints. The composite product is made in several ways, including lamination at roll caster rolls, and lamination or thermal spraying at the exit side of a roll caster. The invention additionally provides for an angulation rolling method for varying percent of cladding on the composite, and a high-manganese aluminum alloy useful as core material in brazing sheet clad with aluminum-silicon brazing alloy.
