Our Products — Custom Rare Earth Magnets for Every Application

Samarium Cobalt (SmCo) Magnets

At The Samarium Magnet Company, we produce custom Samarium Cobalt magnets tailored to exact dimensional, magnetic, and environmental specifications:

Sintered SmCo: for dense, high-strength applications
Bonded SmCo: combining SmCo powder with epoxy or other binders for slightly flexible shapes and complex geometries
Hot-pressed SmCo: providing higher energy density and precision-tuned magnetic performance.

Samarium Cobalt (SmCo) magnets are high-performance, hard, and reliable, engineered for extreme conditions. Renowned for exceptional temperature stability and corrosion resistance, these magnets excel in aerospace, defense, nuclear, and demanding industrial applications. They operate continuously above 350 °C and tolerate peaks up to 550 °C, far exceeding the limits of standard Neodymium magnets.

Samarium Iron Nitride (SmFeN) Magnets

At The Samarium Magnet Company, we produce custom SmFeN (Samarium Iron Nitride) bonded magnets tailored to exact dimensional, magnetic, and environmental specifications:

Isotropic SmFeN: for cost-effective applications requiring uniform magnetic properties
Anisotropic SmFeN: delivering higher magnetic strength and directional performance
Injection-molded SmFeN: enabling complex geometries, tight tolerances, and high-volume production

Samarium Iron Nitride (SmFeN) magnets are high-performance, cost-efficient, and thermally stable, engineered as an advanced alternative to bonded Neodymium magnets. Known for superior corrosion resistance, higher Curie temperature, and excellent thermal stability, SmFeN magnets excel in automotive, electronics, sensors, motors, and demanding industrial applications. With a Curie temperature reaching 476 °C, SmFeN magnets maintain magnetic performance at temperatures far beyond the limits of bonded Neodymium materials—without the use of cobalt or heavy rare-earth elements.

Neodymium (NdFeB) Magnets

At The Samarium Magnet Company, our Neodymium Iron Boron (NdFeB) magnets are custom-manufactured with full attention to every engineering specification and performance requirement.

Sintered NdFeB: Dense, high-strength magnets ideal for high-performance motors and advanced systems.
Bonded NdFeB: Magnetic powder combined with resins, enabling complex geometries and partial flexibility.
Hot-pressed NdFeB: Engineered for superior energy density, thermal stability, and precision performance.

Neodymium (NdFeB) magnets are the strongest permanent magnets available, delivering unmatched magnetic energy for motors, actuators, robotics, and precision sensors. Renowned for their exceptional power density in compact designs, these magnets excel in applications where maximum strength and performance are critical. Standard grades operate up to 150 °C, while high-temperature variants—enhanced with heavy rare earth elements like Dysprosium (Dy) and Terbium (Tb)—perform reliably up to 230 °C.

Custom Coated & Plated Magnets — Even for Single-Unit Orders

Have a small order or prototype request? We’ve got you covered. The Samarium Magnet Company supports low-volume and custom magnet production, offering the same precision and quality as our large-scale manufacturing runs. We believe great partnerships start small — just promise us that if you love our magnets, you’ll come back for more!

Our proprietary coating and finishing technologies let you tailor the look and performance of your magnets:

Protective finishes: nickel, gold, zinc, and epoxy coatings for durability and corrosion resistance.
Color customization: up to 8 paint colors for Neodymium magnets and unlimited patina options for buck-ball and decorative forms.
Advanced processes: PVC coating, electroplating, and even paint-baked finishes — including on ferrite magnets, which are typically non-conductive and rarely coated.
