powercore® K grades
Semi-processed powercore® grades display good processing properties in the as-delivered condition. The magnetic properties are developed by annealing the individual stampings or the complete stack at the customer’s plant.
In many cases, the core losses are lower and the polarization values higher than the values specified in the standards.
