FINEMET FINEMET Nanocrystalline Fe-based Soft Magnetic Material with High Saturation Flux Density, High Relative Permeability and Low Core Loss What is FINEMET The precursor of FINEMET is amorphous ribbonnoncrystallineobtained by rapid quenching at one million / second from the molten metal consisting of Fe, Si, B and small amounts of Cu and Nb. These crystallized alloys have grains which are extremely uniform and small, about ten nanometers in size. Amorphous metals which contain certain alloy elements show superior soft magnetic properties through crystallization. It was commonly known that the characteristics of soft magnetic materials are larger crystal grains yield better soft magnetic properties. Contrary to this common belief, soft magnetic material consisting of a small, nano-order, crystal grains have excellent soft magnetic properties. Features. 2. 3. 4. 5. 6.. Satisfy both high saturation magnetic flux density and high permeability High saturation magnetic flux density comparable to Fe-based amorphous metal. High permeability comparable to Co-based amorphous metal. 2. Low core Loss /5th the core loss of Fe-based amorphous metal and approximately the same core loss as Co-based amorphous metal. 3. Low magnetostriction Less affected by mechanical stress. Very low audio noise emission. 4. Excellent temperature characteristics and small aging effects Small permeability variationless than ±%at a temperature range of -5050. Unlike Co-based amorphous metals, aging effects are very small. 5. Excellent characteristics over wide frequency range High permeability and low core loss over wide frequency range, which is equivalent to Co-based amorphous metal. 6. Flexibility to control magnetic properties B-H curve shape during annealing Three types of B-H curve squareness, high, middle and low remanence ratio, corresponding to various applications 2
