High Saturation Magnetic Flux Density Permalloy 1J22 Series for Aerospace Motors
Product Summary: Our Permalloy 1J22 series, including grades 1J22, 1J22MS, and 1J22HS, offers ultra-high saturation magnetic flux density (Bs up to 2.35 T) combined with low coercivity and high Curie temperature. This makes it ideal for high-performance applications such as aerospace motors, magnetostrictive transducers, magnetrons, and precision electromagnets. Available as strip, wire, or customized stampings.
Key Selling Points
Ultra-High Saturation (Bs 2.35 T): Enables stronger electromagnetic attraction and downsizing of motors and electromagnets, proven in aerospace generator and precision motor projects.
Low Coercivity (Hc ≤ 8 A/m): Minimizes hysteresis loss, ensuring long-term stable operation under alternating magnetic field cycles.
High Curie Temperature (950°C): Maintains magnetic stability up to 180°C short-term, suitable for severe environments.
Multiple Strength Grades: 1J22 for standard, 1J22MS for optimized magnetic domain response, 1J22HS for ultra-high mechanical strength (tensile up to 1200 MPa).
Wide Operating Temperature: -60°C to 120°C continuous, with no performance degradation under aviation-grade vibration.

Models and Options
Available in grades 1J22 (standard), 1J22MS (optimized magnetic domain for dynamic response), and 1J22HS (enhanced mechanical strength for high-speed rotation). Forms: strip, wire, bar, stamped parts.
An aerospace component manufacturer used our 1J22HS grade for electromagnet pole heads in satellite actuators. The high tensile strength (1200 MPa) and consistent magnetic properties enabled reliable operation under high centrifugal force, with a lifespan exceeding 15 years.
FAQ
What is the difference between 1J22, 1J22MS, and 1J22HS? 1J22 is standard. 1J22MS has optimized magnetic domain for faster dynamic response in torque motors. 1J22HS offers higher tensile strength for high-speed rotating parts.
Can you provide custom stampings? Yes, we can supply stamped or laser-cut parts per drawing.
What is the typical lead time? 10-25 days depending on quantity.
Do you have certifications? We have in-house B-H tester and mechanical testing. Third-party inspection accepted.
Is the material suitable for high-frequency applications? Effective up to 1 MHz due to low core loss (8-35 W/kg at 1 kHz, 0.2 T).
What is the MOQ? 50 kg for standard products.
Can I get a sample? Yes, sample available with freight collect.
