XGS-32H & XGS-32 Samarium Cobalt Magnets

The Samarium Magnet Company supplies XGS-32 and XGS-32H high-temperature samarium cobalt (Sm₂Co₁₇) magnets for demanding applications requiring high magnetic performance and temperature stability. XGS-32 provides a maximum energy product of 30–32 MGOe with a maximum operating temperature of 300°C, while XGS-32H provides 30–32 MGOe and is rated for temperatures up to 350°C. Both grades are available in custom magnet shapes, dimensions, and magnetization configurations for OEM, engineering, industrial, aerospace, motor, rotor, oil and gas, and other high-temperature applications. With supply exported from Saudi Arabia rather than China, The Samarium Magnet Company provides customers with an alternative sourcing channel for XGS-32 and XGS-32H SmCo magnets and avoids reliance on the Chinese export-license process for our Saudi-origin magnets.
