Advantages and Usage Considerations of Samarium-Cobalt Magnets

After thousands of years of development, magnets have become a powerful material in our daily lives. By synthesizing alloys of different materials, the same effect as magnetite can be achieved, and the magnetic force can also be increased. Artificial magnets appeared in the 18th century, but the process of manufacturing stronger magnetic materials was very slow until aluminum-nickel-cobalt was produced in the 1920s. Then, in the 1950s, ferrites were manufactured, and in the 1970s, rare earth magnets, including neodymium-iron-boron and samarium-cobalt, were produced. At this point, magnetic technology has developed rapidly and strong magnetic materials have made components more miniaturized.


What is samarium cobalt magnet?


Samarium-cobalt magnets and neodymium-iron-boron magnets are both powerful magnets, but usually more information is provided about neodymium-iron-boron magnets. Many people want to learn about samarium-cobalt magnets but do not know where to start. Samarium-cobalt magnetis a kind of magnet made from raw materials of samarium, cobalt, and other rare earth metal materials. Before making the magnet, the raw materials need to be crushed, molded, and sintered. Nowsamarium-cobalt magnets are also commonly used in industries such as aviation, communication, machinery, motors, and so on, and the demand is quite large. Many companies need to use samarium-cobalt magnets. What are the advantages of samarium-cobalt magnets? What should be noted about samarium-cobalt magnets?


What should be noted about samarium cobalt magnet?


  • Although samarium-cobalt magnets have very good coercivity and good temperature stability, they are easy to peel off. When handling them, magnet manufacturers remind the operator to wear protective goggles.

  • When the operator takes out the samarium-cobalt magnet, it needs to be gently placed and not to use an iron workbench. In addition, a cushion should be placed between two magnets, otherwise, if the samarium-cobalt magnets collide with each other, it may cause the magnet itself to break and lead to danger.

  • Manufacturing of samarium-cobalt magnets is called sintering process. These raw materials alloys are usually processed in a non-magnetized state. Magnet manufacturers need to use wet fine grinding (water-cooled heat dissipation) and diamond grinding wheel for samarium-cobalt during production. Due to its low ignition point, samarium-cobalt is easily ignited if it is not dried.


What are the advantages of samarium cobalt magnet?


  • Although the magnetic force of samarium-cobalt magnets is not as strong as that of neodymium-iron-boron magnets, samarium-cobalt magnets have a wide range of working temperatures and have good temperature coefficients. Magnet manufacturers believe that if the product is used at very high temperatures, samarium-cobalt magnets can be selected;

  • In addition to performing well at high temperatures, samarium-cobalt magnets can also maintain their strong magnetism under low temperature environments. Many customers who have asked whether they can use them in low-temperature environments have chosen them;

  • The application of samarium-cobalt magnets is currently very extensive, especially in high-temperature environments, such as automotive engines, sensors, motors, ships, food manufacturing, and more.
