As these formed compound alloys must be kept below 1 micrometer in size, these compounds are responsible for increasing the hysteresis losses and decreasing the material's permeability. Grain size in Aokelan grain oriented transformer steel is always in larger and uniform sizes due to large grain size magnetic losses being reduced.
Aokelan electrical steel for transformer cores comes in a normal range of 0.3 mm to 0.25 mm. These materials are stacked or wound together to give the transformers and other electrical devices a strong magnetic core. In general, for silicon steel production, 3% of the silicon composition for Aokelan CRGO silicon steel is considered better as more silicon makes the sheet very brittle, which increases the electrical resistivity and decreases the losses due to eddy current.
