DuraFlux™

Distributed air gap toroid cores made from a complex composition of Silicon iron and pure iron powders are compacted into toroid shapes. The unique combination of high saturation flux density and high dc bias capability makes DuraFlux cores an ideal choice for demanding high energy storage applications. DuraFlux materials have an initial permeability of  60µi  with standard core sizes from 6.35mm to 100.0mm. Cores are coated with an epoxy coating which provides a tough outer surface with a minimum breakdown voltage of 500Vac. DuraFlux cores are colour coded in green.
