SmCo magnet

View large

SmCo magnets including SmCo5 and Sm2Co17 based on the different components.The physical character and ductibility of SmCo5 is better than Sm2Co17, so SmCo5 is slightly easier to be machined thin thickness disc or ring wall and complex shapes while Sm2Co17 is more brittle.

Sm2Co17 maximum working temperature 350C.Sm2Co17 bears a extremely low temperature coefficient and preferably anti-causticity. In high-temperature conditions, the magnetic properties is better than NdFeB magnets.

SmCo Magnet Advantages

We can make mass production for high grade YXG-32 with BH>=29MGOE consistently and stably as U.S and Japan standard
We can make big size product up to 120x120x100MM with full magnetization
We can produce SmCo magnets through axial with many poles
We can offer the magnets with deviation less than 2°between mechanical axis and magnetic axis.
We can produce big size magnet with very strict tolerance up to+/-0.01mm and the crack within 1x1x1MM

SmCo magnet Application Field

It needn't to be coated because it is difficult to be eroded and oxidzed. SmCo magnet is widely used in space probe,national defense and military,microwave appliance,communication,medical equipments,motors,instruments.

: Motor application

: Aviation application

: Military application

: Instrumentation application
