近几年来由于Fe—Cr—Co永磁合金可加工而其性能又相当于铸造AlNiCo_5合金,受到国内外的重视。目前磁能积已达到5×10~6高斯·奥斯特以上,而磁场处理后再变形的Fe—Cr—Co永磁合金则为(B·B)_(ma)7×10~6高斯·奥斯特[1]。此合金可进行热、冷加工,轧制,拉拔,车削成棒,细丝、板、薄带等,为电子电讯工业的发展,为各种仪器仪表永磁元件形状的复杂化提供了物质基础。
In recent years due to Fe-Cr-Co permanent magnetic alloy Machinable and its performance is equivalent to casting AlNiCo_5 alloy, by domestic and foreign attention. At present, the magnetic energy product has reached above 5 × 10 -6 Gauss Oersteds, and the deformed Fe-Cr-Co permanent magnetic alloy after magnetic field treatment is (B · B) _ (ma) 7 × 10 -6 Gauss Auster [1]. The alloy can be hot, cold working, rolling, drawing, turning into rods, filaments, plates, ribbons, for the development of the telecommunications industry, for a variety of instrumentation, the complexity of the shape of the permanent magnet element provides the material basis .
