    Publication number: 20010007846
    Abstract: A method of fabricating a circular-shaped metal structure, includes the steps of (a) rotating a pipe around an axis thereof, the pipe being composed of a plastic-workable metal, and (b) applying drawing to an outer wall of the pipe with the pipe being kept rotated, to reduce a wall thickness of the pipe and lengthen a wall of the pipe. A resultant circular-shaped metal structure fabricated by the method could have a thickness equal to or smaller than 0.09 mm.
