isovac 400-50 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.Upon request, isovac 400-50 A can be supplied with an electrical steel insulation system and can be used directly in as-delivered condition.

Convincing advantages: » 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 perfect solution for direct application
