Abstract:
A method for manufacturing an Al clad product comprising the steps of:a) extruding a base material having Al; b) fusing and coating cladding material on the base material; c) coating slurry material on the cladding material coated on the base material, the slurry material including mixture of a flux powder, a resin binder powder and a diluent; d) hardening the slurry material to thereby provide a hardened product including the base material, the cladding material and hardened slurry material; and e) brazing the hardened product to thereby provide an Al clad product, wherein the hardening step (d) is carried out through the use of heat originated from the extruding step (a), and the diluent included in the slurry material is gasified in said step (d) and the cladding material is fused by employing an arc discharge technique.
