AI Overview

Mu-metal stamped cores are high-permeability, soft magnetic Nickel-Iron (Ni80) alloy components used for precision magnetic shielding and flux concentration in sensitive electronics. Commonly stamped as laminations or stacked in EE shapes, they offer high linearity, very low hysteresis loss, and low coercivity, making them ideal for hall sensors, clamp ammeters, and small transformer cores.

Key Characteristics & Advantages

High Permeability: Exceptional magnetic shielding effectiveness and magnetic conductivity, particularly in weak fields.
Material: Usually made from Ni80 permalloy (Mu-metal) to achieve high linearity, crucial for sensing and measurement devices.
Production Method: Stamped laminations are stacked or wound (thicknesses of 0.2 mm or 0.35 mm).
Properties: Offers low remanence, minimal magnetic losses, and low coercivity, crucial for efficiency in sensitive applications.

Common Applications

Current Transformers: Used in high-accuracy current transformers for power distribution.
Hall Sensors & Ammeters: Utilized as Flux Concentrators (magnetic collectors) in Hall effect-based current sensors and clamp ammeters.
Magnetic Shielding: Shielding sensitive equipment against stray DC and AC fields.
Components: Used in small transformer cores, relays, and stepper motors.

Customization
Stamped cores, often produced by manufacturers like Hongertech, are customized to specific sizes and performance requirements, with typical production lead times for custom orders being within 4 weeks.
