They are resistant to high temperatures and are most efficient at temperatures between 523 K and 853 K. Samarium cobalt magnets are remarkably strong permanent magnets. The downside of using this type of samarium cobalt magnet is that it is susceptible to corrosion when it comes in contact with water because it contains traces of iron. Its maximum energy product is 20 to 32 MGOe. Although this type of samarium cobalt magnet was discovered after SmCo 5, it has gained wider popularity for being stronger. This implies that two samarium atoms are added per seven atoms of cobalt. In this type of samarium cobalt magnet, the ratio of samarium to cobalt is 2:7. This type of samarium cobalt magnet is highly resistant to corrosion. Its maximum energy product is 15 to 24 MGOe. However, it is no longer used frequently because the second type of samarium cobalt magnet has overtaken it. This type of samarium cobalt magnet was discovered before the other type. This means five cobalt atoms are used for every atom of samarium used. In this type of samarium cobalt magnet, the ratio of samarium to cobalt is 1:5. Samarium cobalt magnets are classified into two based on the ratio of samarium to cobalt used during production. Samarium Cobalt Magnets Types of Samarium Cobalt Magnets Before the invention of this magnet, the Alnico magnet was more widely used. Samarium cobalt magnet is the first rare-earth magnet to be used commercially. This magnet was formulated by Karl Strnat and Alden Ray in the early 1970s. In the production of this magnet, the Samarium portion can be replaced with cerium, praseodymium, and gadolinium, while the cobalt portion can be replaced with transition metals. They are one of the rare-earth magnets and are typically made from Samarium and Cobalt.
Samarium cobalt magnets are permanent magnets.
