SmCo Blocks

Sintered Anisotropic Samarium Cobalt – Blocks

Rare Earth Sintered SmCo Blocks are high-performance magnets manufactured from sintered anisotropic samarium cobalt. These blocks are produced by diamond slicing larger ingots and then magnetising them, allowing for the production of custom sizes quickly. Rare Earth Sintered SmCo Blocks

Samarium Blocks

Magworks LLC offers a variety of Samarium Cobalt (SmCo) block magnets, including the popular General Grade 2:17 28/20. However, our range extends to other grades such as 1:15 XG 20/20, ensuring we can meet a wide spectrum of requirements.

The SmCo block magnets we display are just a segment of our comprehensive standard high-temperature block magnet collection. If the size you’re seeking isn’t among the options listed, we encourage you to reach out to us with your specific needs. Our team is adept in custom designing, engineering, and supplying Samarium magnets to align perfectly with your unique demands.

Samarium block magnets are renowned for their ability to function effectively at temperatures up to 350°C. They offer exceptional resistance to corrosion and demagnetisation, and maintain their magnetic potency over time. While sintered Neodymium magnets have a higher magnetic energy density per volume, Samarium is the go-to material for applications in challenging or high-temperature environments.

These magnets are widely used across various industries, including aerospace, motors and generators, sensors, research, and manufacturing, particularly in scenarios where exposure to extreme temperatures or harsh elements exceeds 100°C.

We are committed to providing expert advice to help you choose the most suitable Samarium magnet for your application. Contact us to benefit from our expertise and explore our full range of Magnet Materials and Products for more options and solutions.
