Ferrites (iron oxides) are known for their high rate of electrical resistance and high magnetic permeability, and they are used in many applications ranging from medical devices to transmission antennae.

Machining Degree of Difficulty
Ferrites, or Iron Oxide compounds, are ceramic-like materials best known for their electrical resistivity and magnetic permeability. These characteristics allow for ferrite components to be created that can prevent eddy currents or switch magnetism with minimal energy loss, or to effectively concentrate a magnetic field for data transmission via mediums such as radio waves. As an iron-based ceramic, there are a number of different grades and types of ferrite, with low coercivity ferrite being known as “soft” ferrite, and high coercivity known as “hard” ferrite. Outside of pure ferrite, manganese-zinc and nickel-zinc ferrites are commonly used in component manufacture as well.

Ferrite components are commonly used in a variety of settings, including everything from electronic applications and telecommunication, to pot cores and switching power supplies, to inductive sensor applications in the medical industry. Ferrite’s machinable nature allows for exacting tolerance requirements, so it is a frequent choice for engineers and designers looking for ferrite’s unique material characteristics.
