Ni-Alloy Steel Transformer Core has been produced with a material(what is called 'Permalloy'), made of Iron. Nickel and other elements. with high permeability. low coercive force and hysteresis. The material is one of soft magnetic material is classified into several types based on the composition of Nikel, Iron and others and used widely in various magnetic parts which are especially communication, small power Transformer Core and Chokes.

* Products
- EI, EX, EL and EE-Core for Transformer.
- Various Magnetic-Shielding Cases and Deflection Yoke Core.
