Samarium cobalt magnets
Samarium cobalt (SmCo) magnets offer strong magnetic properties and excellent temperature resistance, making them ideal for demanding environments where other magnets may lose performance. Available in cylindrical, rectangular, and ring shapes, these magnets are widely used in motors, generators, measuring instruments, electronic components, and medical devices. Their corrosion resistance and thermal stability make them a preferred choice for applications that require reliable magnetic performance under extreme conditions.
