Oriented electrical steel

CLIK offer a wide choice of Grain Oriented electrical steels. All manufactured to the highest quality standards, Unisil is conventional grain oriented material between 0.23mm and 0.35mm thick and Unisil-H is high permeability  grain oriented steel at a maximum thickness of 0.30mm. The product range also includes laser scribed products, which offer improved loss performance over traditional Unisil-H, through  a sophisticated process of domain refinement. 


Grain Oriented electrical steel is an essential material in the manufacture of energy efficient transformers and large, high performance generators. Its unrivalled magnetic properties are a result of its unique grain structure, which is formed through a complex production process starting from high silicon hot rolled coil feedstock. During the secondary recrystalisation process some grains grow to over 30mm in length. Whereas mild steels require a microscope to view the grain structure. The orientation of the enhanced grain structure provides significantly better magnetic properties in the rolling direction of the sheet.


Grain Oriented electrical steels are normally used in applications where they are magnetised under AC conditions. Low power loss and high permeability characteristics are advantageous where energy efficiency, low noise and core size are important. These applications include:

• Power generators • Large power transformers • Distribution transformers • Small transformers • Current transformers • Shunt reactors • Wound cores
