DEFINITION

Classification: 164/91

(under subclass 47) Process of making multi-layered articles by forming a metal onto a preform or casting two or more metals into contact with one another.

(1) Note. A composite article must have at least two distinctive zones of metal of the same or different materials. If solids of the same metal or different metal are incorporated into cast molten metal and such lose their identity this is not a composite for this and indented subclasses.

(2) Note. Included herein are those operations where two or more metal preforms are united by fusing a portion of the metal to provide a joint between them.
