Description
Hiperco27 is a new kind of soft magnetic alloy and also called FeCo27. while its permeability and the coercive force slightly smaller than hiperco50, but the mechanical toughness and ductility is better, can be competent for machining, the saturated magnetic induction intensity and Curie temperature are fairly to HiperCo50 .
