23Q090
23Q090 Grain-Oriented Electrical Steel
The thinnest grade in the range, for large power transformer cores where eddy current loss dominates the loss budget.
View details27Q100 Grain-Oriented Electrical Steel
27Q100 sits between the conventional 0.30 mm grades and the thinnest material in the range. Reducing gauge lowers eddy current loss, which allows a lower no-load loss at the same core dimensions.
The grade is supplied slit to width for winding or cutting lines, with coating options matched to the core building process and mill test certificates issued per coil.
