  • Thermal annealing

    Please note, that with very few exceptions soft magnetic alloys, and in particular finished parts, need to be treated with a thermal annealing to obtain the desired magnetic properties.

Properties of material

Compared to MUMETALL®, PERMENORM® 5000 H2 with its higher iron content has a higher saturation magnetisation and is therefore suitable primarily for applications in which stronger magnetic fields play a role. PERMENORM® 5000 H2 too does not usually need surface treatment to protect against corrosion.

The higher iron content also has disadvantages, however. Its dynamic properties (at higher magnetic field frequencies) are not as good as with MUMETALL®, and coercive field strength and therefore core losses are greater.

Apart from actuators and yokes, PERMENORM® 5000 H2 is often used in the area of magnetic shielding for medium and higher field strengths.
