AI Overview
High-precision mu-metal stators, typically constructed from 80% nickel-iron alloy (Ni80), offer superior magnetic permeability for high-accuracy flux concentration, specifically for hall sensors, clamp ammeters, and current sensors. These stators, often designed as stacked laminations (0.2–0.35 mm thickness), provide high linearity and very low hysteresis. Custom-made L-shape or stacked cores are specialized for high-speed, non-contact current sensing, with manufacturers offering production within 4 weeks.
Key Features and Applications
- Material Characteristics: High initial permeability and high shielding efficiency are essential for low-intensity fields.
- Applications: Ideal for sensitive electronic equipment requiring EMI protection, such as medical electronics, power systems, and aerospace components.
- Manufacturing Techniques: Often produced via stamping, deep drawing, or stacking of laminations followed by necessary [Perfection Annealing] to maximize shielding performance.
- Components: Used in precision instruments to block magnetic interference.
Customization and Manufacturing
- Production: Tailored for small production runs, prototyping, and large-volume industrial manufacturing.
- Shapes: Available in specialized forms such as L-shape stamped cores, stacked cores, and customized geometries for specific sensors.
- Finishing: Annealing is required after machining, stamping, or welding to restore magnetic properties.

What metal has the highest magnetic permeability?
Mu-metal
Mu-metal is a soft magnetic alloy with exceptionally high magnetic permeability. The high permeability of mu-metal provides a low reluctance path for magnetic flux, leading to its use in magnetic shields against static or slowly varying magnetic fields.
