摘要:
The present invention provides a material which can be used for low pressure molding, and which has a low core loss while maintaining the characteristic of an amorphous powder that is the high coercive force. It provides a magnetic powder material containing, relative to the weight thereof, amorphous powders of 45 to 80 wt %, crystalline powders of 55 to 20 wt %, and a bonding agent. The magnetic powder material contains, relative to the mass thereof, Si of 4.605 to 6.60 mass %, Cr of 2.64 to 3.80 mass %, C of 0.225 to 0.806 mass %, Mn of 0.018 to 0.432 mass %, B of 0.99 to 2.24 mass %, P of equal to or less than 0.0248 mass %, S of equal to or less than 0.0165 mass %, Co of equal to or less than 0.0165 mass %, and a balance of Fe and inevitable impurities.
