The specialist with the highest permeability

isovac® is the electrical steel made by voestalpine and stands for highest energy efficiency. With its

excellent attribute profile, isovac® provides a higher level of quality that will help you remain a step

ahead of the competition.

This non-grain-oriented, full-finished isovac® grade is produced on one of the world‘s most modern

continuous annealing lines and features a specially adjusted microstructure and texture achieved by a

special annealing process that increases both flux density and magnetizability across the entire range

of the magnetic field. The higher permeability of isovac HP 350-65 A makes it possible to reduce

machine size while maintaining the same amount of torque.

Convincing advantages p Production in one of the world‘s most modern continuous

annealing lines with widths of up to 1650 mm

p Higher rotational speeds/torques with increased output based on higher magnetizability (up to 0.06 T at J25/50/100)

p Machine downsizing for reduced material consumption, lower weight and minimized space requirements
