49 % Cobalt-Iron-Alloys
VACOFLUX and VACODUR for High Performance Motors
49 % cobalt-iron alloys, such as VACOFLUX® and VACODUR®, are characterized by a high magnetic saturation of up to 2.3 T. Therefore, they 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 and yield superior performance parameter for electrics motors and generators.
VACODUR alloys exhibit strength properties required for applications such as high speed rotating machines by using our recommended annealing temperatures.

Lamination Stacks
Lamination stacks are packages using single laminations separated by electrical insulating layers to surpress eddy current losses during dynamic magnetic load.
VACOFLUX® X1
High performance combined with low weight is a key 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.
9 to 27 % Cobalt-Iron
VACOFLUX grades with low cobalt content have been developed to offer an attractive price level for clearly defined applications.
