It has been found that duplex monolithic parts can be manufactured in high volume at low cost by using powder metal technology to mold and sinter an inner component of the part into an outer component of the part. This technique reduces the cost of manufacturing intricate metal products by taking advantage of the attributes of powder metal technology in making the inner component of the part. The outer component of the part can be wrought machined, stamped or forged, or made by double press double sinter or forging a powder metal component of the part. In any case, this technique can beneficially be used in making a wide variety of toroid parts, such as gears, clutches, sprags, bearing races, one-way diodes, and the like.
