SmCo Cylinder Magnet 6.35mm x 12.7mm YXG28

SmCo Cylinder Magnet – 6.35mm x 12.7mm | YXG28

The SmCo Cylinder Magnet – 6.35mm x 12.7mm | YXG28 is a premium Samarium Cobalt (SmCo) rare earth permanent magnet designed for high-performance applications where exceptional thermal stability, corrosion resistance, and long-term magnetic reliability are essential. Measuring 6.35mm in diameter and 12.7mm in length, this precision-engineered cylinder magnet is ideal for demanding industries including aerospace, medical technology, industrial automation, electronics, scientific research, and precision engineering.

Manufactured from YXG28 grade Samarium Cobalt, this magnet provides strong and stable magnetic performance while offering excellent resistance to demagnetisation, oxidation, and corrosion. Unlike many neodymium magnets, SmCo magnets naturally resist rust and chemical attack, meaning they typically require no protective coating, making them an excellent choice for harsh operating environments.

The magnet is axially magnetised, with the north and south poles located on the two flat circular faces. This produces a focused magnetic field along the length of the cylinder, making it well suited for precision holding, positioning, sensing, coupling, actuating, and magnetic assembly applications.

Whether incorporated into high-temperature equipment, sensitive instrumentation, electric motors, or custom engineering projects, the 6.35mm x 12.7mm SmCo Cylinder Magnet delivers dependable magnetic performance where reliability is critical.

Why Choose a Samarium Cobalt Cylinder Magnet?

Samarium Cobalt magnets are the preferred choice for applications where long-term magnetic stability and environmental durability are more important than maximum magnetic strength alone. Their exceptional resistance to heat, corrosion, oxidation, and demagnetisation makes them particularly valuable in demanding industrial and scientific environments.

Unlike standard neodymium magnets that typically require protective coatings, SmCo magnets naturally resist corrosion, making them suitable for use in humid environments, chemically aggressive conditions, vacuum systems, and high-temperature applications without the risk of coating failure.

Manufactured from YXG28 grade Samarium Cobalt, this cylinder magnet provides reliable magnetic performance throughout its service life, making it ideal for precision equipment, industrial machinery, aerospace systems, medical technology, and advanced electronic devices where consistent operation is essential.

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.

Although SmCo magnets offer excellent resistance to corrosion and high operating temperatures, they should not be drilled, machined, or cut after manufacture, as this may permanently damage the magnet and generate hazardous dust.

Magnetic performance will vary depending on the application design, mating material, operating temperature, air gap, and alignment.

Keep magnets away from pacemakers, medical implants, magnetic storage media, and sensitive electronic equipment. Exercise care when handling multiple magnets, as they can attract each other with considerable force.
