Abstract
Metal injection molding was used to produce near-net-shape parts made of an Fe-6.5%Si soft magnetic alloy having a low workability due to its high degree of hardness and brittleness.
We attempted metal injection molding using powders with the larger, 20 μm (-350 mesh) average particle size generally used in powder metallurgy. We studied the effects of different powder properties on kneadability and moldability. Results of experiments showed that the 20 μm average particle size can be used in injection molding if given a high tap density.
