As the second generation of rare earth permanent magnets, Samarium Cobalt (SmCo) not only has high magnetic energy product (14-32 MGOe) and reliable coercivity, but also shows good temperature characteristics in rare earth permanent magnet series. Compared with NdFeB, Samarium Cobalt is more suitable for working in a high temperature environment.
Samarium Cobalt magnets consist mainly of samarium and cobalt.
Samarium Cobalt magnets for sale are likewise the most expensive of several magnets because of the high cost of the two materials themselves. The magnetic energy product of Samarium Cobalt magnet can be owned by 30 MGOe, or even higher.
In addition, Samarium Cobalt magnet has high coercivity and high temperature resistance, which can be implemented to 350 degrees Celsius high temperature, so it can not be replaced in many applications. Samarium Cobalt magnet is a powder metallurgical product. Generally, depending on the size and shape of the finished product, the manufacturer sinters the block blank, and then uses the diamond blade to cut into the finished product size. Because Samarium Cobalt is conductive, it can be treated with WEDM.
In theory,
Samarium Cobalt can be reduced into shapes that can be cut by WEDM without considering magnetization and larger size. Samarium Cobalt magnet has excellent corrosion resistance and generally does not require anticorrosive plating or coating. In addition, the Samarium Cobalt magnet is very brittle, so it is difficult to process small size or thin-walled products.
