49 % Cobalt IronVACOFLUX® and VACODUR®

Thanks to their high magnetic saturation of up to 2.4 T, the cobalt-iron (CoFe) alloys VACOFLUX® and VACODUR® are generally suitable for all applications where high flux density and minimum weight are required.

Our alloys with cobalt content of 49 % and 2% vanadium offer low coercivity forces and yield superior performance parameter for electrics motors and generators.

40 % to 50 % Nickel Iron

Alloys with a Ni-content of around (40...50) wt% are characterized by a maximum in the saturation polarisation of up to JS = 1.6 T and a medium range permeability. By selecting appropriate rolling and annealing conditions, the shape of the magnetization curve can be varied over a wide range.

69 % to 82 % Nickel Iron

These high permeability materials differ mainly in the level of permeability. Permeability increases in the series from the standard grade MUMETALL® to the highest grade ULTRAPERM® 250. VACOPERM® 100 D is a solid material.

Nanocrystalline MaterialVITROPERM®

VITROPERM® is an iron-based nanocrystalline material with an outstanding combination of soft-magnetic properties which make it the state-of-the-art material for a wide range of applications, e.g. common mode chokes (CMCs), current transformers (CTs), EMI filters and shielding material in wireless power transfer.

Amorphous MaterialVITROVAC®

VITROVAC® alloys are magnetically soft but mechanically hard, with a high elastic limit. Properties comprise highest saturation flux density and excellent permeability, making it the ideal solution for applications like electronic article surveillance, flexible antennae, magnetic sensors, magnetic shielding, switching cores in accelerators or power transformers.
