铁铬钴磁铁(FeCrCo magnet）是永磁中的变形金刚，合金永磁可变形之最，可以拉丝（0.2-0.3mm）拉管 轧带 以及各种机械加工。A.FeCrCo(铁铬钴)变形永磁合金具有较高的磁性，可与AlNiCo永磁合金媲美，但其含Co量要比AlNiCo低50%左右。B.FeCrCo合金具有优良的塑性与延展性易于加工，这是铸造永磁合金无法比拟的特性，而该合金较高的使用温度400左右，又是NdFeB稀土永磁不可及的。C.FeCrCo合金经加加工可制成丝、棒、管、带和锻材，经车、铣、刨、钻和冲压等机械加工，能制成各种形状复杂的永磁元件，尤其对细小、长薄元件显示出独有的特性。最薄的带材可以达到0.05mm，最细的丝材可以加工成到0.1mm.
FeCrCo magnet is the transformer of permanent magnet. The alloy permanent magnet can deform the most. It can draw wire (0.2-0.3mm) for tube rolling and various machining. A. FeCrCo (Fe Cr CO) deformed permanent magnet alloy has higher magnetic properties, which is comparable to alnico permanent magnet alloy, but its CO content is about 50% lower than alnico. B. FeCrCo alloy has excellent plasticity and ductility and is easy to be processed, which is incomparable to cast permanent magnet alloy, and its higher service temperature is about 400, which is beyond NdFeB rare earth permanent magnet. C. FeCrCo alloy can be processed into wire, rod, tube, strip and forging material. After turning, milling, planing, drilling and stamping, it can be made into permanent magnetic elements with complex shapes, especially for small, long and thin elements. The thinnest strip can reach 0.05mm, and the thinnest wire can be processed to 0.1mm
