It is widely used in the cores of communication transformers, magnetic heads, and as a meterials for magnetic shielding cases. |
| Ni-Alloy steel transformer core has been produced with a material (called 'Permalloy'), made of iron, nickel and other elements with high permeability, low coercive force and hysteresis. The material is a type of soft magnetic material and is classified into several types. These types are based on the composition of nickel, iron and others and used widely in various magnetic parts which are common in communication equipment components, small power transformer cores and chokes. |
