Iron-based Powder Solutions For Soft Magnetic Composite Applications

The recent acceleration in interest and market demand in hybrid and fully electric vehicle systems has brought new opportunities to the PM market for use of Soft Magnetic Composite (SMC) materials. As greater acceptance of these materials in both the industrial and automotive market continues, products which serve specific industry needs are being developed and standardized for use. The success of SMC powders for these specific applications is based on three important inputs – base iron, insulating coating and lubricant. Thermal processing of the SMC compact also plays a critical role, as material deformation behavior has a direct impact on magnetic properties. These factors and their influence on final properties will be discussed.
