ABSTRACT:
A method of making twin roll cast clad material includes producing a composite material using a liner stock produced by drag casting techniques. The drag cast liner stock can be directly used in a twin roll continuous casting process without additional process steps such as heat treatment, surface cleaning and/or rolling. The drag cast liner stock can be applied to one or both of the surfaces of the twin roll cast material to produce a composite material that is useful in a cast form or can be adapted for reduction by rolling processes or the like. The twin roll cast cladding process can utilize aluminum alloy core and cladding materials to form a brazing sheet from the as-cast composite material.
