Silicon steel

Silicon steel is an iron‑silicon soft‑magnet alloy with silicon added to reduce core loss and boost magnetic permeability. Commonly used in power grid, new‑energy vehicle and electrical equipment fields.

Low magnetostriction silicon steel coil

Oriented Electrical Steel-27QG100

Through in-depth research on the influence factors of magnetostriction, the magnetic striction of the silicon steel with low noise characteristics developed can be reduced by 3-5dB(A) compared with the conventional. The transformer and reactor products with low noise characteristics of the silicon steel can reduce the overall noise of the product by 2-3dBA.
