Samarium cobalt magnet, mainly composed of samarium and cobalt.
1. Samarium cobalt magnet, mainly composed of samarium and cobalt. The samarium cobalt magnet is also one of the most expensive of the several magnets, since the materials themselves are expensive. The magnetic energy product of samarium cobalt magnets is currently 30MGOe, or even higher.
2. In addition, samarium cobalt magnets have high coercivity and high temperature resistance. They can be used at high temperatures up to 350 degrees Celsius, so they cannot be replaced in many applications. Samarium cobalt magnet belongs to powder metallurgy products. Generally, according to the size and shape of the finished product, the manufacturer burns the blank into a square, and then uses the diamond blade to cut into the size of the finished product. Because of its conductivity, samarium cobalt can be used for wire cutting.
3. In theory, samarium cobalt can be cut into shapes that can be cut by wire cutting, if magnetization and larger size are not taken into account. Samarium cobalt magnet, corrosion resistance is very good, generally do not need to be anticorrosive plating or coating. In addition, samarium cobalt magnets are brittle, making it difficult to process small or thin-walled products.
