Ferrite rings, due to their shape, are widely used because they can adapt to different applications compared to magnets of traditional shape.
The rings can have the magnetic poles oriented axially (through the thickness), diametrically (dividing the diameter in two) or radially (along the radius).
They are immediately recognizable by their dark grey color.
The main strengths of this magnetic material are its total resistance to rust and corrosion, its high maximum operating temperature (up to 250 °C) and its competitive price.
Although they do not boast a high attraction force, they are suitable for many industrial sectors, most notably electric motors and generators, hi-fi and sound systems, sensors, medical equipment, advertising, etc.
All the magnets on this page are made of Y30BH ferrite and have axial magnetization, but the list of products available in stock is long and we have other sizes and other types of magnetization available.
