SmCo magnets are the second generation of rare earth permanent magnet from magnetndfeb.com

SmCo magnets are the second generation of rare earth permanent magnet , is divided into 1:5 type (SmCo5) and 2:17 (Sm2Co17) two kinds. Its main feature is magnetic , good temperature performance. The maximum operating temperature can reach 350 °. Compared with NdFeB magnets, SmCo magnets better suited to work in high-temperature environments. SmCo is suitable for the manufacture of various high-performance permanent magnet motor and the working environment is very complex applications. In addition , samarium cobalt magnets rust capability, which generally does not require plating surface treatment, unless there are special requirements .

Nature samarium cobalt magnet cobalt : cobalt steel gray metallic with shiny , melting point 1493 ℃, specific gravity 8.9 , relatively hard and brittle, Cobalt is ferromagnetic , hardness , tensile strength, machinability , thermodynamic properties , the electrochemical behavior similar to iron and nickel . When heated to 1150 ℃ magnetism disappears. Valence cobalt is divalent and trivalent . And water is not the role of the moist air is also very stable at room temperature . When heated in air above 300 ℃ oxidation of CoO, Co3O4 during combustion to incandescence . Hydrogen reduction process into a fine cobalt metal powder in the air can be spontaneous generation cobalt oxide.

SmCo magnets are mainly used in a variety of sensors , motors, automotive components , micro-motors , sputtering equipment, magnetic devices , aerospace and other special requirements for temperature field . Because there is radiation samarium cobalt magnet function and, therefore, widely used in spacecraft and other fields.

China Rare Earth Magnet Limited - magnet company , specializing in the production of magnetic materials manufacturer, specializing in the production of rare earth permanent magnets , such as sintered NdFeB magnets , Bonded NdFeB magnets, SmCo magnets and Alnico magnets. We also supply ferrite magnets, rubber magnets and magnetic properties of some of the components .

Founded in 1985 , and more than 39,000 square meters of room , equipped with a neodymium magnet on hand related to 3000 annual manufacturing capacity. Due to enhanced technology and improved internal management has to be completed in the summer of 1998 passed ISO9002 licensed , and with ISO 9000 amounts related to the 2000 version of the plan to modify at 06 in 2001 , by 2005 the TS16949 permission. China Rare Earth Permanent Magnet Co., Ltd. , another takes great focus on environmental safety as well as demand-based manufacturing execution procedures related purely to ISO14001 . Up until now , China Rare Earth Permanent Magnet Co., Ltd. , can give a lot more than 10 patents in the permanent magnetic field such as crystallization and shooting method for injection , which is the processing power and high-power magnets such as N52, 50M -related production orders , 48H, 45SH, 40UH and 38EH and so on. In the case of the client request , we can provide Sumitomo Corporation (SSMC) NdFeB magnetic obvious.
