An improved casting nozzle for continuous slab casting machines is provided. The nozzle includes a sloped surface which reduces molten metal turbulence during the casting process. The nozzle also includes a resilient, thermal insulation layer which prevents undesired backflow and premature solidification of the molten metal near the nozzle tip. The nozzle may also include a friction reducing layer which prevents excessive wear or fracture of the nozzle as it contacts the casting mold. The casting nozzle is suitable for use with both horizontal and vertical continuous casting machines, and may be used with various types of casting molds including continuous belt or caterpillar molds, and stationary molds. The improved nozzle may be used to cast various metals such as aluminum and aluminum alloys.

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.
