SmCo Disc Magnet 8mm x 5mm

Samarium Cobalt (SmCo) Disc Magnet – 8mm x 5mm

The Samarium Cobalt (SmCo) Disc Magnet – 8mm x 5mm is a premium rare earth permanent magnet designed for high-performance applications where exceptional thermal stability, corrosion resistance, and long-term magnetic reliability are essential. Manufactured from high-quality Samarium Cobalt (SmCo), this precision disc magnet measures 8mm in diameter and 5mm thick, making it ideal for industrial automation, aerospace, medical devices, scientific instrumentation, sensors, and precision engineering projects.

Unlike conventional neodymium magnets, Samarium Cobalt magnets are specifically engineered to maintain stable magnetic performance at elevated temperatures while offering outstanding resistance to corrosion, oxidation, moisture, and many aggressive chemicals. This makes them an excellent choice for demanding environments where reliability is critical and protective coatings may not be suitable.

The magnet is axially magnetised, with the north and south poles located on the two flat circular faces. This magnetic orientation provides a concentrated magnetic field, making the magnet suitable for magnetic holding, sensing, positioning, coupling, and precision assembly applications.

Whether you're developing advanced electronic devices, manufacturing specialised machinery, designing aerospace components, or building laboratory equipment, the 8mm x 5mm Samarium Cobalt Disc Magnet delivers dependable magnetic performance with exceptional durability.

Please Note

Samarium Cobalt magnets are hard and brittle and should be handled with care to avoid chipping or cracking if dropped or allowed to snap together. Do not drill, machine, or subject the magnet to excessive impact, as this may permanently damage the material.

Although SmCo magnets naturally resist corrosion and typically do not require a protective coating, they remain powerful permanent magnets and should be kept away from children due to the serious swallowing hazard posed by small magnets.

Keep away from pacemakers, implanted medical devices, sensitive electronic equipment, and magnetic storage media. Actual magnetic holding performance will vary depending on the thickness and quality of the steel surface, air gaps, mounting configuration, operating temperature, and surrounding materials. For the best performance and longest service life, install the magnet in a way that minimises mechanical stress and protects it from sudden impacts.
