Ceramic Magnets | Ferrite Industrial Permanent Magnets
Ceramic magnets, also known as ferrite magnets, are a cost-effective and durable magnetic material used across a wide range of industrial, commercial, and high-volume applications.
They offer dependable magnetic performance, excellent corrosion resistance, and strong resistance to demagnetization. Ceramic magnets are a practical choice when moderate magnetic strength, temperature resistance, and long-term value are more important than maximum pull force in the smallest possible package.

Frequently Asked Questions
What are ceramic magnets made of?
Ceramic magnets, also known as ferrite magnets, are made from iron oxide combined with barium or strontium carbonate.
How strong are ceramic magnets compared to neodymium magnets?
Ceramic magnets are not as strong as neodymium magnets, but they are lower cost, naturally corrosion resistant, and better suited for some higher-temperature or high-volume applications.
What temperature can ceramic magnets operate at?
Ceramic magnets are commonly used in higher-temperature environments than standard neodymium magnets. Application conditions should still be reviewed before final selection.
Do ceramic magnets corrode?
Ceramic magnets are naturally corrosion resistant and typically do not require protective plating or coating.
Can ceramic magnets be machined or drilled?
No. Ceramic magnets are hard and brittle and cannot be machined with conventional tooling. They should be manufactured, cut, or ground to size using proper processes.
When should I choose ceramic over neodymium?
Choose ceramic magnets when cost, corrosion resistance, temperature resistance, and larger working air gaps are more important than having the highest possible pull force in the smallest magnet.
Are custom sizes and shapes available?
Yes. Ceramic magnets can be sourced or produced in a wide range of standard and custom shapes, including blocks, rings, discs, arcs, and assemblies.
