Product Description
Product Overview
Permalloy 80 is a nickel-iron soft magnetic alloy composed of approximately 80% nickel and 20% iron. This specialized material offers exceptional magnetic properties ideal for precision industrial applications requiring high efficiency and reliability.
Key Properties
Permalloy 80 delivers superior performance through its unique combination of magnetic characteristics:
- High magnetic permeability for effective magnetic field conduction
- Low coercivity requiring minimal magnetization energy
- Near-zero magnetostriction for dimensional stability
- Significant anisotropic magnetoresistance for sensing applications
- Face centered cubic crystal structure with 0.355 nm lattice constant
