Properties

Non-oriented fully processed high permeability electrical steels have guaranteed magnetic properties significantly superior to the requirements of EN 10106:2015, particularly regarding the polarisation levels obtained. Full magnetic characterisation curves are available on request, as well as thermal conductivity data. The thermal conductivity of these steels is also higher than the conductivity of the fully processed standard grades.

Advantages

The high permeability levels of these grades allow a reduction of the magnetising current required for a given air gap flux. This increases the efficiency of the machine and also makes it possible to increase its specific power rating, thereby reducing the machine's dimensions. High thermal conductivity levels are important, since they facilitate heat evacuation from the machine.

Applications

High permeability is particularly useful for applications such as ballasts and motors, because it makes it possible to build machines that meet the most stringent environmental regulations. High thermal conductivity is a significant advantage for large machines.

Recommendations for use

The above properties are obtained without heat treatment after stamping. The material as supplied possesses all the required magnetic properties.
