Product Description
1J85 Soft Magnetic Alloy is a precision-engineered nickel-iron (Ni-Fe) based alloy renowned for its exceptional soft magnetic properties, including ultra-high saturation magnetic flux density and extremely low coercivity. This alloy maintains outstanding magnetic performance across a wide operational range, establishing itself as a fundamental material for high-efficiency transformers, sensitive sensors, and critical components in aerospace and telecommunications.
1j85 Soft Magnetic Alloy is particularly valued for its unparalleled combination of high permeability, minimal core loss, and excellent magnetic stability. Its excellent ductility and workability facilitate the fabrication of complex core shapes required in advanced electromagnetic designs.
Enables the design of smaller, more powerful magnetic components with high efficiency due to its ability to handle strong magnetic fields. This is critical for miniaturization in advanced electronics and power devices.
Ensures easy magnetization and demagnetization with minimal energy loss, leading to high sensitivity and responsiveness in sensors and instruments. High permeability allows for efficient magnetic flux conduction.
Exhibits minimal dimensional change under magnetization, virtually eliminating vibration and audible noise ("hum") in transformers and inductors, essential for precision and quiet operation.
Allows for relatively easy cold working and fabrication into complex shapes like thin strips, laminations, and precision cores required for sophisticated electromagnetic designs.

Our Advantage
Here are 5 key application fields for 1J85 Soft Magnetic Alloy, presented bilingually with concise explanations suitable for product listings:
Its high sensitivity and low coercivity make it ideal for high-accuracy current sensors, fluxgate sensors, and critical components in navigation systems (e.g., gyroscopes), ensuring reliable and precise measurements.
Used in sensitive relays, magnetic shielding, and control system components within satellites, aircraft, and guidance systems, where reliability, stability, and performance under demanding conditions are paramount.
Essential for high-frequency transformers, inductors, and chokes in switch-mode power supplies (SMPS), inverters, and converters, enabling smaller size, higher efficiency, and lower losses compared to ferrites at high flux densities.
Employed in components like magnetic amplifiers, pulse transformers, and high-Q inductors for filtering and signal conditioning in communication equipment, ensuring signal integrity and low distortion.
Its near-zero magnetostriction minimizes audible transformer hum and vibration, making it critical for high-fidelity audio transformers, video head cores, and other components demanding silent operation and high signal quality.
