ABSTRACT:
A clad wire having a cast metal core with a formed sheath intimately bonded to the core with the interface portions thereof being effectively free of intermetallic compounds. The clad product may be formed by the steps of forming a strip of first metal into a closed tube, introducing a fused second metal into the tube from a position upstream of the tube and causing the fused second metal to quickly solidify within the tube while effectively causing a separation of the tube and core interface portions for a sufficient short period of time to permit the core temperature to drop below the temperature at which intermetallic compounds of the core and sheath tube material readily form.
