In this paper, the chemical composition, physical properties,microstructures and magnetic properties of Fe-24Cr-15Co-2Mo-0. 5Ti alloy used asa permanent magnet are discussed. Its magnetic properties are: Br=14800 Gs, Hc=680 Oe, (B. H)_m=7.4×10~6 GOe. Its equiaxed grain alloy met the level of alnico5alloy. Sensitively of columnar grain alloy is 10～20% better than alnico5 alloy onthe CD-6-F fluctuation measuring meter. The various requirements of equiaxed grainalloy may be obtained on the wide angle meter or UQK-32 float meter. Both alloyshave used as a magnet on φ 57mm and φ 77mm loudspeakers, interval density (Bg=5000Gs or 5500Gs) of which achieved entirely among 53 specimens. Finally, theanalysis of application and investigation of these alloys is discussed.
