SmCo20 Samarium Cobalt Magnets

SmCo20 samarium cobalt magnets are high-performance permanent magnets designed for applications requiring reliable magnetic properties, resistance to demagnetization, and performance in demanding environments. The SmCo20 family includes SmCo20, SmCo20H, SmCo20L, and SmCo20LT, giving engineers multiple grade options to evaluate against their application's magnetic requirements and operating conditions. The Samarium Magnet Company supplies custom SmCo20 magnets for aerospace, defense, electric motors, generators, sensors, oil and gas, and industrial equipment. Magnets can be manufactured to customer-specified shapes, dimensions, tolerances, and magnetization directions. Contact The Samarium Magnet Company to discuss your SmCo20 requirements and request a custom quotation.
