SmCo Disc Magnet 3mm x 2mm XGS26

Samarium Cobalt (SmCo) Disc Magnet – 3mm x 2mm | XGS26

The Samarium Cobalt (SmCo) Disc Magnet – 3mm x 2mm | XGS26 is a compact, high-performance rare earth permanent magnet engineered for applications requiring exceptional magnetic stability, outstanding temperature resistance, and excellent corrosion resistance. Manufactured from premium Samarium Cobalt (SmCo) XGS26 material, this precision disc magnet measures 3mm in diameter and 2mm thick, making it ideal for miniature electronic devices, sensors, aerospace components, medical equipment, and other precision engineering applications.

Unlike standard neodymium magnets, SmCo magnets retain their magnetic performance across a much wider temperature range and offer outstanding resistance to corrosion and oxidation without requiring a protective coating. This makes them particularly suitable for use in harsh environments, vacuum systems, marine applications, high-temperature assemblies, and chemically aggressive conditions where long-term reliability is critical.

The magnet is axially magnetised, with the north and south poles located on the two flat circular faces, providing a concentrated magnetic field in a compact form. Despite its small size, the 3mm x 2mm SmCo Disc Magnet delivers reliable magnetic performance while offering exceptional durability in environments where conventional magnets may fail.

Whether you're designing miniature sensors, precision instruments, medical devices, motors, or aerospace equipment, the 3mm x 2mm XGS26 Samarium Cobalt Disc Magnet offers outstanding performance, stability, and longevity.

Why Choose a 3mm x 2mm SmCo XGS26 Disc Magnet?

The 3mm x 2mm XGS26 Samarium Cobalt Disc Magnet is an excellent choice when environmental conditions exceed the capabilities of standard neodymium magnets. While neodymium magnets offer extremely high magnetic strength, SmCo magnets provide superior thermal stability, corrosion resistance, and long-term reliability, making them the preferred solution for demanding industrial and scientific applications.

Its compact size allows it to be integrated into miniature assemblies where space is limited, while the XGS26 SmCo material ensures dependable magnetic performance even when exposed to elevated temperatures, moisture, vacuum environments, or corrosive chemicals.

For applications where reliability, precision, and environmental resistance are more important than maximum magnetic strength, Samarium Cobalt magnets provide an outstanding long-term solution.

Please Note

Samarium Cobalt magnets are hard and brittle and should be handled carefully to avoid chipping or cracking if dropped or allowed to snap together. They should not be drilled, machined, or subjected to excessive mechanical impact.

Although SmCo magnets offer exceptional corrosion resistance and generally do not require protective plating, they remain powerful permanent magnets and should be kept away from children due to the serious swallowing hazard posed by small magnets.

Keep magnets away from pacemakers, implanted medical devices, sensitive electronic equipment, and magnetic storage media. Actual holding force will vary depending on the thickness and quality of the steel surface, air gaps, mounting configuration, and operating conditions. For optimum performance and longevity, install the magnet in a manner that minimises impact loading and mechanical stress.
