Ferrous Powder in Magnetic Applications for the Automotive Industry

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.
