isovac® is the non-grain-oriented electrical steel made by voestalpine and stands for highest energy efficiency. Electrical steel is a material used in many different forms in the construction of magnetic cores in electrical appliances and machinery. voestalpine is Europe's market leader for non-grain-oriented semi-finished electrical steel.
isovac® made by voestalpine is a high-quality electrical steel for electric motors, generators and transformers of all kinds.
The high demands of motors in general and especially drive motors in the field of e-mobility are met by isovac® with respect to efficiency and performance, highest permeabilities, lowest losses and, where required, high strength.
Together with the pole plates of voestalpine, isovac® electrical steel makes a significant contribution in generator design with respect to increases in the efficiency of a wide range of generator types and sets new standards in terms of performance and sustainability.
The specialists of voestalpine are continually developing and optimizing special high-quality isovac® grades for static machines such as transformers, reactance coils or magnets for particle accelerators.
Customized solutions are indispensable in a dynamic market marked by a wide variety of individual demands. With respect to compact engine design and high efficiency, voestalpine has just the right product for each customer.
The insulating varnish applied to the strip surface is a key factor in the highest performance of machines made of isovac® electrical steel. This is why voestalpine also relies on the highest quality of the insulating varnish systems. In close collaboration with leading European varnish manufacturers, voestalpine supplies insulating varnishes that contain no toxins, carcinogens, mutagens, formaldehyde or chromium compounds. The coatings meet all applicable EC directives (RoHS Directive 2011/65/EC).
Consistent mechanical properties across the entire length of the strip and clean surfaces that cause minimal abrasion on the punching tool are prerequisites to optimized punching processes.
The result of our stable and continuous rolling process is a reduction in the steel strip thickness tolerance value. Subsequent continuous annealing reduces material stress to a minimum. This enables voestalpine customers to manufacture components with the highest precision.
