Permalloy can be divided into 4 categories according to composition: 35%~40% Ni-Fe alloy, 45%~50% Ni-Fe alloy, 50%~65% Ni-Fe alloy and 70%~81% Ni-Fe alloy . Each type can be made into materials with circular hysteresis loop, rectangular hysteresis loop or flat hysteresis loop.

Permalloy strip is an alloy material with high magnetic permeability and high permeability. Its characteristics are: 45%-81% NI medium nickel and high nickel soft magnetic alloy: Bs=0.7-1.6T. The magnetic permeability ranges from 50,000 to 50,000. 500,000, using different
The production process and heat treatment system can obtain ordinary loop-high initial permeability, rectangular loop-high residual magnetic induction, and flat loop-low residual magnetic induction. High magnetic induction, high magnetic permeability and low loss to reduce the weight and volume of magnetic components. Mainly used for metal shields.
Permalloy are used to harvest energy the electromagnetic ring with 1J85 grade strips:
