Metallic fiber (steel wool), bundle drawn from larger diameter wire (smallest fiber is produced by this method), cast from molten metal, or grown around a seed (often carbon). Bundle drawn metal fiber can be produced to sizes smaller than one micrometre in diameter.

Metlon Corporation is one of the remaining manufacturers in the U.S. that stocks a wide variety of laminated and non-laminated metallic yarns & Brightex Corporation, Japan and South Korea, such as Hwa Young, is also manufacturing Metallic fibers.
