Nickel-Zinc (Ni-Zn) Ferrite

Ni-Zn ferrite is a grade of ferrite. The graph bars on the material properties cards below compare Ni-Zn ferrite to other oxide-based engineering ceramics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
