Sm2Co17 Magnet

SmCO magnets include SmCo5 magnets and Sm2Co17 magnets according to different composition.

Sm2Co17 Magnets are made from  Samarium(Sm) , Cobalt(Co), iron(Fe) and Zirconium(Zr), The (BH)max range from 20 to 32MGOe, maximum working temperature up to 350°C. Because of  great brittleness of Sm2Co17 materials,  it is not suitable for complicated shapes and thin thickness for block and disc or  thin wall ring SmCo Magnets.

SmCo5 Magnets are mainly made  from  Samarium(Sm), Cobalt(Co).Sometimes,the rare earth metal – praseodymium(Pr) is also needed. The (BH) max range is from 16 to 25MGOe, maximum working temperature can up to  250°C. SmCo5 Magnets is slightly easier to be machined into thin thickness disc, thin wall ring  and complex shapes than Sm2Co17 magnets  because their ductibility is better than  Sm2Co17 magnets’ . But Magnetic properties of SmCo5 is lower than Sm2Co17’s.

Various shape available, such as block ,ring , arc ,trapezoid ,and so on. Dimension and propeties  can be according to customer requirement.

 High grade SmCo magnets with (BH)max>32MGOe

Become following feature of SmCO magnets with 32MGOe: 1. The Price is even cheaper than N35EH,N35AH of Neodymium magnets in 2011 ; 2. The magnetic properties in high temperature is better than Neodymium magnets’s;3.They even do not need coating base on good corrosion resistance,They can instead of Neodymium magnets to using in all kinds of motor ,generator very well.
