Soft Magnetic Materials and Stamped Parts
Lamination Stacks
Lamination stacks are packages using single laminations separated by electrical insulating layers to surpress eddy current losses during dynamic magnetic load.
Soft Magnetic Stamped Parts
All crystalline alloys can be processed further to stamped parts. VAC has state-of-the-art facilities for punching, deep-drawing and further processing methods like interlocking or wire-EDM.
49 % Cobalt Iron 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.
9 % to 27 % Cobalt Iron VACOFLUX
The low cobalt content VACOFLUX® qualities were developed to offer
an attractive price level for well defined applications.
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. A very versatile group of magnetic materials characterized by a saturation polarization of up to 1.55 T, high permeabilities and remarkably low specific losses.
77 % to 82 % Nickel Iron
MUMETALL®, VACOPERM® 100, ULTRAVAC® 80, and CRYOPERM® exhibit extremely low coercivities and highest permeabilities and are therefore often the first choice for magnetic shielding and many other sophisticated applications.
Nanocrystalline Material VITROPERM
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 Material VITROVAC
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.
VACOFLUX X1
High power combined with low weight is a central feature of motors built with this new low-cobalt-content alloy. Typically, motors can be realised that have a 20 to 30 % higher power density than with electrical steel.
