Ferrite magnets, also known as ceramic magnets, are durable and cost-effective permanent magnets widely used in industrial, commercial, and high-volume applications. Their excellent resistance to corrosion, reliable magnetic performance, and economical material cost make them a practical choice when the extremely high strength of neodymium magnets is not required.

Radial Magnets supplies ferrite and ceramic permanent magnets in a range of shapes and sizes for production, OEM, prototyping, replacement, and bulk purchasing requirements.

Why Choose Ferrite Magnets?

Ferrite magnets are commonly selected for applications where durability, corrosion resistance, temperature performance, and cost are more important than achieving the highest possible magnetic strength.

Key advantages include:

• Excellent resistance to corrosion
• No protective plating required for most environments
• Cost-effective for high-volume applications
• Stable magnetic performance
• Good resistance to demagnetization
• Suitable for many elevated-temperature applications
• Available in multiple shapes, dimensions, and configurations

Ferrite Magnets vs. Neodymium Magnets

Ferrite magnets are generally weaker than neodymium magnets of the same size, but they offer several important advantages.

Neodymium magnets provide extremely high magnetic strength in a compact package, while ferrite magnets typically offer lower material cost, excellent corrosion resistance, and dependable performance for applications where maximum magnetic energy is unnecessary.

Common Ferrite Magnet Applications

Ferrite permanent magnets are used across a wide range of industries, including:

• Electric motors and generators
• Speakers and audio equipment
• Sensors and switches
• Magnetic separators
• Holding and positioning assemblies
• Automotive components
• Industrial equipment
• Appliances
• Educational and laboratory applications
• High-volume consumer products

Because ferrite magnets contain no rare-earth materials, they can also provide an attractive alternative when customers are looking to reduce dependence on rare-earth magnet supply chains.

Frequently Asked Questions

Are ferrite magnets and ceramic magnets the same thing?

Yes. The terms ferrite magnet and ceramic magnet are commonly used interchangeably for this family of permanent magnets.

Are ferrite magnets permanent magnets?

Yes. Ferrite magnets are permanent magnets and maintain their magnetic field without requiring an external electrical power source.

Are ferrite magnets stronger than neodymium magnets?

No. Neodymium magnets generally provide substantially greater magnetic strength for a given size. Ferrite magnets can be preferable when cost, corrosion resistance, or application conditions are more important than maximum magnetic strength.

Do ferrite magnets rust?

Ferrite material has excellent natural corrosion resistance and normally does not require the nickel, epoxy, or other protective coatings commonly used on neodymium magnets.

Can Radial Magnets supply custom ferrite magnets?

Yes. Custom dimensions, shapes, magnetization requirements, and production quantities can be sourced for qualifying applications. Contact Radial Magnets with your specifications or drawing for assistance.
