Ferrite Ring Shape Magnets Can Improve Your Product

These magnets are typically magnetized through their thickness (axial magnetization), meaning the magnetic poles are located on the flat faces of the ring. This configuration is beneficial for applications requiring magnetic fields to pass through the ring's hollow center.

One of the major advantages of ferrite magnets, including ring shapes, is their affordability. Ferrite materials are relatively inexpensive to produce compared to rare earth materials, making ferrite ring magnets an economical choice for manufacturers and end users. Their low cost enables their use in high-volume applications without compromising budget constraints.

Ferrite magnets are inherently resistant to corrosion and oxidation, unlike some metal-based magnets which require protective coatings. This resistance makes ferrite ring magnets suitable for use in humid or mildly corrosive environments without the need for additional surface treatment. This property also contributes to their durability and long service life.

Ferrite magnets generally operate well at elevated temperatures, often up to around 250°C (482°F), depending on the grade. They maintain their magnetic properties better than some other types of magnets when exposed to heat, making them useful in applications where thermal stability is important.

While ferrite ring magnets are mechanically hard, they are also brittle and can be prone to cracking or chipping if handled roughly. This characteristic requires careful manufacturing, handling, and installation practices to avoid damage. Despite their brittleness, their hardness helps them maintain shape and performance in demanding environments.

Perforated ferrite permanent magnets are widely used in Microwave, Antenna, Electronics, and Communication industries. The perforated ferrite permanent magnet features a high permeability and high coercivity. Their main features include small size, lightweight, superior performance characteristics, and suitability for several application areas. They can be used to improve the product's efficiency and reduce or even eliminate external interference caused by eddy currents.
