Complex shapes can be obtained at high production rates using powder metals that are blended with a polymer or wax (see PIM in Fig. 17.14 on p. 495). Also, the

  • Powder Metallurgy For Manufacturing

    Some tests unique to powders may also be used. For example, an iron powder may have an unknown percent of iron oxide, (Fe 2 O 3). A test sample of the iron powder is taken and exposed to a stream of hydrogen. Weight loss that occurs in the sample is measured. From this, the percentage of iron oxide present in the powder can be calculated.
