9 to 27 % Cobalt-Iron VACOFLUX

Cost Optimized Cobalt-Iron Alloys with a High Saturation Polarization

Cobalt-Iron alloys in general have a very high polarization saturation. This group of CoFe alloys, with a reduced cobalt content of 9 - 27% cobalt, are optimized to meet the requirements of technically demanding, however cost sensitive applications.

 

Benefits:

  • Reduced cost level due to lower cobalt contents
  • Optimized product parameters for dedicated applications

Strip material

  • Electric motors and generators (VACOFLUX X1)
  • Magnetic actuators (VACOFLUX 17, 18 HR and 9 CR)

Solid material

  • Magnetic actuators (VACOFLUX 17, 18 HR and 9 CR)
  • Flux guiding parts (VACOFLUX 27)

    Strip Rods / Wires
VACOFLUX X1 New alloy which is closing the gap between electrical steel and 49 % cobalt-iron qualities  
VACOFLUX 17 Cost optimized cobalt-iron grade for magnetic actuators
VACOFLUX 18 HR Special cobalt-iron quality with outstanding resistivity of 0.6 µΩm for high dynamic applications  
VACOFLUX 9 CR Corrosion resistant material for applications in aggresive enviroments

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.
