Product introduction

Permalloy is a soft magnetic alloy primarily composed of iron and nickel, featuring exceptionally high magnetic permeability and extremely low coercivity, making it the ideal material for magnetic shielding and magnetic flux guidance in weak magnetic field environments. Our Permalloy plates are available in four commonly used thicknesses: 1.0mm, 1.5mm, 2.0mm, and 3.0mm. The standard width can reach up to 600mm or more, with length customizable according to requirements, and the maximum available size is 2000mm×1000mm. Manufactured using precision cold-rolling techniques, our products offer excellent surface flatness and strict thickness tolerance control, ensuring stable and reliable magnetic performance.

KEY FEATURES:

• Ultra-high initial permeability, offering sensitive response in weak magnetic fields;

• Extremely low coercivity, enabling easy magnetization and demagnetization;

• Low hysteresis loss, effectively reducing energy loss during cyclic magnetization and improving device efficiency;

• Near-zero magnetostriction, ensuring minimal dimensional change during magnetization and excellent dimensional stability;

• Excellent workability, with high plasticity supporting stamping, bending, laser cutting, spot welding, and other processing methods.

TYPICAL APPLICATIONS:

• Magnetic shields and enclosures, used in precision electronic equipment, medical MRI devices, and avionics navigation instruments to protect sensitive components from stray magnetic field interference;

• Transformer and inductor cores, suitable for high-frequency low-voltage transformers, current transformers, common-mode chokes, ground fault interrupters, and other magnetic devices;

• Sensors and precision instruments, used in fluxgate magnetometers, audio transformer cores, recording heads, and other weak magnetic field detection and signal conversion applications;

• Military and aerospace, applied in gyroscope shielding cases, satellite electromagnetic shielding components, and other applications demanding stringent magnetic shielding performance.
