Permalloy Core Iron-Nickel Alloy For Current Transformer
Permalloy is essentially an iron-nickel (FeNi) alloy with very low coercivity, while the saturation magnetic density Bs, permeability and Curie temperature are all high, close to pure iron. Multi-element permalloy, the initial relative permeability can reach 30,000 to 80,000, but the resistivity is low, about 10-7Ω-m, it can be processed into very thin slices, so it can be used up to (20-30) kHz working frequency. Permalloy thin strips with a thickness of 0.02mm are commonly used in domestic engineering, and there are also 0.005mm thick thin strips. However, due to the insulation of the surface of the thin strip during the winding process of the magnetic core, its filling factor is greatly reduced, so in engineering rarely use. When the application frequency exceeds 30kHz, due to the low resistivity of permalloy, its loss will increase significantly.
