Cogent Power's Unisil product range enables our customers to use electrical steels with the best magnetic properties, confident in the knowledge that the materials are supported by reliable delivery and strong technical support.

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 re-crystalisation 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.
