Malleable and ductile cast irons are used extensively in automotive applications such as clutches, gears, carriers, shafts, bearings, cam, racers, hubs, etc. Recently developed P/M materials can be processed cost efficiently to replace malleable and ductile iron castings. An UTS in excess of 1240 MPa and a YS in excess of 825 MPa can be achieved with one of these new materials. These tensile properties can be coupled with elongations over 2% and impact energies over 25 Joules. This presentation will cover processing routes for these new materials and will identify parts that may benefit from this new technological advancement.

The usage of powder metallurgy in automotive electromagnetic applications has increased dramatically. The combination of P/M's unique shaping making capability, the efficiencies of the process and the design flexibility of the materials have opened significant growth opportunity. Magnetic applications via P/M need not be limited to DC applications; the recent development on non-sintered P/M materials permits their usage in AC applications. This paper will document the current uses of P/M in both DC and AC applications.
