High Permeability Transformer Soft Magnetic Core Material Current Transformer Core Permalloy

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.
