AI Overview
1J79 Mu Metal (often referred to as Permalloy 80) is a nickel-iron soft magnetic alloy containing approximately 79% nickel and 4-5% molybdenum, designed for maximum permeability and low coercivity. 1J79 shielding foil is used in the electronics industry for suppressing magnetic field interference, particularly around high-frequency inductors, transformers, and sensitive sensors.
Key Characteristics and Specifications
- High Permeability: Exceptional efficiency in shielding, particularly in low-intensity fields.
- Flexibility: Thin (typically 0.05 mm to 0.25 mm) and lightweight, allowing it to be easily wrapped around small electronic components like inductors.
- Composition: $\sim$79% Ni, 4–5% Mo, Balance Fe.
- Performance: Provides high magnetic flux attenuation with low energy loss (low coercive force).
- Condition: Supplied in a stress-annealed state, but often requires final annealing to reach maximum effectiveness.
Applications for Inductors and Electronics
- Inductor Shielding: Used to wrap around common-mode inductors and coils to prevent magnetic crosstalk and reduce electromagnetic interference (EMI).
- Transformer Protection: Shields high-frequency, low-voltage transformers and small power converters.
- EMI Reduction: Protects sensitive magnetic sensors and circuits, offering a shielding efficiency often exceeding 96% when properly utilized.
- Aerospace & Defense: Used in space exploration devices due to high-temperature stability.
Handling and Manufacturing
- Fabrication: Easily cut, bent, and soldered.
- Post-Processing: Fabrication (bending, stamping) can degrade the magnetic properties, usually necessitating a final, high-temperature hydrogen annealing process to restore maximum permeability.
- Handling: Must be handled carefully to avoid reducing its magnetic performance.
- Thickness: Commonly available in gauges such as 0.05mm.
