High Bs FeSiBPCu Nanocrystalline Wide Ribbons Using Industrial Raw Materials
Nanocrystalline Fe-Si-B-P-Cu wide ribbons, with 15-30mm width, using industrial raw materials have been investigated. A homogeneous nanocrystalline structure composed of α-Fe grains with around 10 nm in diameter was realized after crystallization and the nanocrystalline alloys exhibit the high Bs of 1.74-1.82 T, the low Hc of 6.5-7.2 A/m and the low W at 50Hz-1.7T of 0.42-0.60W/kg. Therefore, the nanocrystalline Fe-Si-B-P-Cu soft magnetic alloy has a large economical advantage of low material cost by using industrial raw materials.
