1J27 Soft Magnetic Alloy

1J27 is a Fe-Co-Cr soft magnetic alloy featuring exceptional ductility and toughness, ranking among the most formable materials in the family of high-saturation magnetic induction and high-Curie-temperature Fe-Co based soft magnetic alloys. Its saturation magnetic induction is nearly equivalent to that of 1J22, while offering significantly better mechanical strength and toughness, thus avoiding the brittleness and cracking tendency often seen in 1J22. 1J27 is ideal for applications that demand a combination of high magnetic saturation, excellent ductility, and superior toughness. Key Properties & Advantages High saturation magnetic induction (comparable to 1J22) High curie temperature, suitable for high-temperature magnetic environments Excellent ductility and impact resistance for demanding applications Low magnetic loss and stable magnetic performance Good processability, suitable for both cold and hot forming Typical Applications Cores and rotors for high-speed electric motors Generators and electromagnetic actuators Aerospace and aviation magnetic systems Precision magnetic components requiring both high saturation and toughness Mechanical Properties (Strip Example) Tensile strength Rm ≤ 570MPa Yield strength Rel0.2 ≤ 400MPa Elongation A ≥ 18% Vickers Hardness ≤ 180HV Supply Forms Specification: strip, sheet, and bar Condition: cold-rolled, annealed Customization: available upon request Standards: specifications available according to Russian, American, British, French, and Japanese standards
