AI Overview
Permalloy wire is a high-permeability nickel-iron alloy (typically $\approx$80% Ni) utilized in specialty electrical transformers, specifically for low-power, high-sensitivity, and precision applications. It excels in reducing core losses, boosting magnetic efficiency in weak fields, and providing shielding in sensitive electronic, audio, and aerospace components.
Key Aspects of Permalloy for Transformers:
- Composition: Frequently 78%-80% Nickel, with iron and additives like Molybdenum () for high magnetic permeability and low coercivity.
