YXG-30H, YXG-30, YXG-30M & YXG-30L Samarium Cobalt Magnets

The Samarium Magnet Company supplies YXG-30H, YXG-30, YXG-30M, and YXG-30L high-performance samarium cobalt (Sm₂Co₁₇) magnets for demanding applications requiring reliable magnetic performance and temperature stability. The YXG-30 family is designed for applications requiring a high energy product in the 28–30 MGOe range, with different grade variants available to meet varying coercivity and temperature requirements. YXG-30 family SmCo magnets are available in custom magnet shapes, dimensions, and magnetization configurations for OEM, engineering, industrial, aerospace, motor, rotor, oil and gas, and other demanding applications. With supply exported from Saudi Arabia rather than China, The Samarium Magnet Company provides customers with an alternative sourcing channel for YXG-30 family SmCo magnets and avoids reliance on the Chinese export-license process for our Saudi-origin magnets.

Note: Our samarium cobalt gets this color because we manufacture everything from scratch with fresh raw materials. We will never sell you the second-handed stuff.
Our complete catalogue of samarium cobalt magnets  →
**This list showcases our most popular samarium cobalt magnet specifications. A full range of chemistries, and custom configurations is available in our complete SmCo magnet catalogue.

YXG-30L → lower-coercivity variant, intended where extreme resistance to demagnetization is less important.

YXG-30 → standard variant, balancing magnetic performance and coercivity.

YXG-30M → higher-coercivity variant than the standard grade.

YXG-30H → high-coercivity/high-temperature variant, intended for more demanding thermal or demagnetization conditions.
