Samarium Cobalt Disc Magnets

Discover our range of samarium cobalt (SmCo) disc magnets, a strong permanent magnet often used in automotive and industrial manufacturing applications. Samarium cobalt is what’s known as a rare-earth magnet, which is a permanent magnet made from alloys of rare-earth elements – in this case, samarium. These types of magnets only lose minute amounts of magnetism over time, making them essential in a huge range of industries.

Samarium cobalt is the second strongest magnet material available commercially, operating at approximately 80% the strength of the stronger neodymium magnets. Although not as strong as neodymium, samarium cobalt magnets can operate at a much wider range of temperatures and are much more resistant to corrosion.

While regular neodymium magnets have a working-temperature limit as low as 80⁰C, samarium cobalt disc magnets can withstand heat up to 350⁰C, making them essential for industries with a high operating temperature. They’re also handy in colder temperatures, with the ability to operate at temperatures nearing absolute zero (-273⁰C).

We have a wide range of sizes of samarium cobalt disc magnets available online, as well as hundreds of more options if you contact us directly. Whatever your project or industry, we’re sure to have a magnetic solution to suit. If you need something outside of our standard range, don’t worry – we also offer custom-made samarium disc magnets, engineered to your specifications.
