isovac high-perm 330-65 A

Manufactured in the most modern production lines, this fully processed isovac® grade exhibits highly homogeneous properties across the width and length of the entire strip. The result is excellent and consistent processability in the manufacture of highly efficient electrical components.The optimum adjustment of texture increases magnetizability and reduces core losses of isovac HP 330-65 A. This increase in efficiency makes it possible to maintain the same level of performance while reducing component size and saving ma-terial, weight and costs. This also means that a higher level of performance can be achieved with the same component size.Upon request, isovac HP 330-65 A can be supplied with an electrical steel insulation system and can be used directly in as-delivered condition.

Convincing advantages: » Increased performance achieved by increasing torque based on higher magnetizability (im-provement by up to 0.05 T at J25, J50, J100)

» Possible cost optimization through less materi-al usage, less weight and less space requirement resulting from downsizing while maintaining the same level of performance

» Best processability through consistent mechan-ical properties and homogeneous, clean sur-faces

» Excellent stackability resulting from high dimen-sional accuracy in rolling direction and perpen-dicular to rolling direction (thickness tolerance)

» Innovative electrical steel insulation systems upon request

The specialist with the highest permeability
