With respect to compact engine design and high efficiency, we have just the right product for each customer. High individual demands on the efficiency and performance of motor steels are met by high permeability, low core loss and, where required, high strengths. Using the most modern technologies in our integrated steelmaking facilities, we manufacture high-quality electrical steel grades to meet your individual product requirements (from Vibracall to industrial motors).
