Samarium Cobalt (SmCo) ring magnets are a type of rare earth magnet made from an alloy of samarium and cobalt. They are known for their impressive magnetic strength and exceptional thermal stability. SmCo magnets can operate at higher temperatures than other rare earth magnets like Neodymium. They are highly resistant to corrosion and do not typically require any surface treatment. This makes them suitable for use in applications where performance and durability under extreme conditions are critical. Common uses include aerospace, military, industrial motors, and various high-performance sensors. SmCo ring magnets are available in various sizes and grades, each tailored to specific performance requirements. Their ring shape is versatile, making them ideal for many magnetic field-focused applications.
