Fluxtrol | Ferrotron 559H Original soft magnetic composite for induction heating

Ferrotron 559H Original

(Frequency: Up to 3000 kHz)

Similar to Ferrotron 559H standard, Original has nearly constant permeability over a wide range of flux densities and excellent machinability. When compared to Ferrotron 559H, Original has better mechanical strength, higher magnetic permeability, saturation flux density and thermal conductivity. These improvements do come at a cost of dielectric strength and magnetic losses.

Note: There are many variables involved in an induction process. In order to utilize the fullest potential of our product, you must help narrow down the parameters you are operating with. Each grade of Fluxtrol material has its own distinctive properties that are beneficial to a certain range of electrical and design parameters.
