SmCo Ring magnets is a kind of rare earth permanent magnet, whose magnetic strength is second only to NdFeB magnet. It has high coercivity (Hcj), high temperature resistance and good corrosion resistance. Samarium cobalt is more suitable for working in high-temperature environment. Samarium Cobalt magnet (SmCo) has two component ratios, SmCo5 and Sm2Co17.
These magnets are commonly used in a variety of applications, including motors, generators, sensors, and magnetic bearings. They are also popular in the aerospace, automotive, and medical industries due to their high-performance capabilities. We can provide our customers with customized samarium cobalt products and related solutions, which are highly resistant to corrosion without coating.
Overall, samarium cobalt ring magnets are an excellent choice for applications that require a high-strength, temperature-resistant magnet that can provide long-term reliability and performance.
