ABSTRACT:
A composite metal article is disclosed comprising at least a first elongated electroformed hollow member and a second electroformed elongated hollow member, each of the hollow members comprising at least a first sleeve and a second sleeve, one sleeve of each of the hollow members having a perimeter larger than the perimeter of the other sleeve of the same member, at least a segment of the outer surface of one sleeve of the second elongated hollow member being adjacent to and substantially surrounded by the inner surface of one sleeve of the first elongated hollow member. This composite hollow member may be formed by electroforming the hollow members on two appropriately shaped mandrels, removing the hollow members from the mandrels, and inserting at least a segment of the hollow member from one mandrel inside at least a segment of the hollow member from the other mandrel whereby the inner surface of at least a segment of the hollow member from one mandrel substantially surrounds at least a segment of the outer surface of the hollow member from the other mandrel.
