Fluxtrol A

Frequency (Up to 100 kHz)

Fluxtrol A has the highest maximum magnetic permeability and the lowest magnetic losses at low to intermediate frequencies in the Fluxtrol family of soft magnetic composites (favorable magnetic direction). Fluxtrol A also has good mechanical strength, thermal conductivity, and is readily machinable. However, it does have high magnetic and thermal anisotropy, which should be taken into account when using the product.

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.
