Square samarium cobalt magnets, a type of rare earth permanent magnet, boast high magnetic energy and an extremely low temperature coefficient. With a maximum working temperature of 350°C, they excel in high-performance applications. Compared to neodymium magnets, these square SmCo magnets outperform in BHmax, coercivity, temperature stability, and chemical resistance, especially at temperatures exceeding 180℃. Notably, they exhibit strong corrosion and oxidation resistance, eliminating the need for plating.
High magnetic performance (high residual flux, high coercivity, high magnetic energy product) with room temperature magnetic properties reaching 35MGOe.
With the highest operating temperature of 550°C, the square samarium cobalt magnets surpass the performance of other magnets.
Strong corrosion and oxidation resistance, requiring no additional anti-corrosion treatment for long-term use.
Extremely low temperature coefficient, typically -0.030%/K."
Various grades of Samarium Cobalt are available for industrial and commercial applications. The magnetic energy of Samarium Cobalt Magnet ranges from 16 to 32 MGOe. The grade range allows for balancing cost, magnetic performance, and operational temperature resistance.
There are two main types of square Samarium Cobalt (SmCo)magnet alloy. The older type, typically denoted as (1-5) has one Samarium atom per 5 Cobalt atoms, and the newer Samarium Cobalt magnet alloy, typically denoted as (2-17), has an atomic ratio of two Samarium atoms to 17 Cobalt atoms.
