Soft Magnetic Alloyed powder
soft magnetic alloys
Fe-Si alloy powder and Fe-Si-Al alloy powder
Advantage:
- Higher DC bias characteristics
- Higher saturation induction density
- Lower core loss
- Better temperature stability
- Better corrosion resistance
- High performance can meet the highest efficiency requirements
- Excellent cost efficiency
Soft magnetic alloys, i.e. Fe-Si alloy powder and Fe-Si-Al alloy powder are two crafts – water atomized powders and gas atomized powders ,Ferrosilicon powder is made by melting a fixed ratio of high purity iron and crude ferrosilicon in an induction furnace. The molten metal is then atomized using a high pressure stream of nitrogen gas to produce a high-grade ferrosilicon powder.
Application of Soft Magnetic Alloyed Powder:
- Traction motors /Air conditioning compressors/Pumps (cooling, oil, etc.)/DC/DC converters/On-vehicle chargers
- Ventilation fans/Solar power/Industrial motor drives/Off-board battery charging
