HXSCO electrical steel coils manufacturer

HXSCO’s cold-rolled electrical steel coils offer high performance and reliability. With a silicon content of 2.8-3.2% and an aluminum content of 0.5-1.2%, they feature ultra-thin consistency (±0.01mm), excellent stamping properties (HV1 170-210), and stable operation over a wide frequency range (50Hz-400Hz). Each coil comes with a C6A or C6F insulating coating for strong protection against corrosion.

We supply directly from the factory, with no middlemen, and offer factory-priced coils (508/610mm ID) with full traceability. Each batch includes a Mill Test Certificate (MTC) detailing the chemical composition and magnetic aging results. We also offer a 3-day sample service for CRNGO and CRGO grades to support rapid development. Our electrical steels are trusted by the energy (transformer winding cores), automotive (electric vehicle motor stator laminations), and HVAC (compressor motor laminations) industries.
