DNF-Iron Silicon Cores Series

Iron Silicon Cores for Industrial-Grade Transformers and Magnetic Assemblies

POURLEROI offers precision-engineered iron silicon cores designed for use in high-efficiency transformers, chokes, and reactors. Manufactured from premium electrical-grade silicon steel, our cores feature low hysteresis loss, high magnetic flux density, and superior thermal stability for demanding industrial power applications.

What Are Iron Silicon Cores?

Iron silicon cores, also referred to as silicon steel cores or electrical steel cores, are made by alloying iron with silicon to improve electrical resistivity and reduce magnetic losses. These cores are typically manufactured using cold-rolled grain-oriented (CRGO) or non-oriented (CRNGO) silicon steel sheets or ribbons. With high permeability and reduced eddy current formation, iron silicon cores are widely used in transformers, inductors, and power conditioning systems that require efficiency, temperature resilience, and electromagnetic stability.

Product Overview

POURLEROI’s iron silicon cores are produced using advanced lamination and strip-winding techniques to achieve uniform magnetic performance, dimensional accuracy, and minimal power loss. We offer a full range of core formats including EI laminations, toroidal cores, C-cores, and custom shapes for specialized transformer and reactor designs.
Our cores are built from high-grade CRGO and CRNGO silicon steel with precise insulation coatings to meet various thermal and dielectric requirements. Typical applications include 50/60Hz distribution transformers, medium-frequency power converters, inverter transformers, and industrial magnetic components.
Each core undergoes quality control for stacking factor, insulation resistance, and core loss metrics. POURLEROI supports bulk orders, quick-turn prototyping, and OEM/ODM customizations for core window size, thickness, and assembly method.
