Product Description

VACOFLUX 27 High Saturation Magnetic Alloy for High Performance Actuator Systems


VACOFLUX 27 offers the highest saturation of all Fe-Co alloys. What's more, it shows an excellent ductility. It is available as hot-rolled, forged bars, cold rolled strips as well as cold drawn wire. Due to the relatively low electrical resistivity, it is commonly used for static applications.


Density: 7.95 g/cm3
Electrical resistivity:19 µΩ - cm
Curie temperature: 925°C
Saturation magnetostriction: 36x10-6
Saturation induction: 23.6kG (2.36T)
Modulus of elasticity: 24 × 106psi (166GPa)
Thermal conductivity: 54.8 W/m·K 
Thermal expansivity, 10-6/°C



Back irons, pole pieces and other flux guiding elements, high power electromagnetic actuators and hydraulic or pneumatic systems

Mainly applications with static fields.

All stamped laminations or machined part must be magnetic annealed after fabrication to develop acceptable magnetic properties.

Anneal part at 760-900°C for 2 to 4 hours in dry hydrogen or vacuum at cool at 80-300°C/h to 300°C 

All parts must be cleaned before annealing.
