isovac 330-35 A HF

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 use of isovac 330-35 A HF (high-frequency) guarantees optimum utilization of the machinery at higher frequencies. High-precision adjustment of the microstructure and adaptation of the alloy content make it possible to keep losses low in the high-fre-quency range. isovac 330-35 A HF is additional-ly characterized by slightly higher strengths.Upon request, isovac 330-35 A HF can be supplied with an electrical steel insulation system and can be used directly in as-delivered condition.

Convincing advantages: » Use in high-speed motors because of low loss-es at high frequencies (up to 10% at 1.5 T and 400/1000 Hz)

» Larger freedom of design and component size optimization resulting from higher strengths as compared to standard isovac® grades

» 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
