These medium-sized samarium cobalt disc magnets maybe thin but they are incredibly dependable. Samarium cobalt is a type of rare-earth magnet that has the ability to withstand and operate in high temperatures and has a superior resistance to corrosion, however they are not as powerful as super-strong neodymium magnets. Because of their high maximum operating temperature they are most often used in applications such as motors and electric motors, turbo machinery and sensors and because of their corrosion resistance they are ideal for use outdoors.
