I. Technical characteristics and product classification<\/h2>\n\n\n\n

Samarium-cobalt permanent magnets are high-performance rare earth permanent magnets made of samarium and cobalt as the main components, together with other elements such as copper, iron, zirconium, etc. These materials have three outstanding characteristics: excellent high temperature stability, excellent magnetic properties and good corrosion resistance. These materials have three outstanding features: excellent high temperature stability, excellent magnetic properties and good corrosion resistance. The upper working temperature can reach 500 degree Celsius, which is significantly higher than that of NdFeB permanent magnets (usually below 220 degree Celsius); in terms of magnetic performance index, the remanent magnetization is not less than 1.05 Tesla, the coercive force is more than 676 kA\/m, and the range of magnetic energy product is between 20-35 MGaust. In addition, Samarium Cobalt permanent magnets are stable in humid and acidic environments without complex surface treatment.<\/p>\n\n\n\n

According to the difference of crystal structure, samarium cobalt permanent magnets are mainly divided into two main types:<\/p>\n\n\n\n
