Product Description
SmCo Magnet
1. Material: SmCo5 and Sm2Co17
2. Shape: Disc, Ring, Block, Abnormity, etc.
3. Size: According to you requirement
4. Future: Super high working temperature, high performance, strong anticorrosion, high precision of all sizes.
5. Application: The electronic magnetron, magnetic transmission, magnetic treatment, magnistor, sensor, etc.
SmCo owns following advantages
. Possess strong magnetic properties - 5-7 times more powerful than ferrite
. Very steady in the conditions capable to cause corrosion
. Possess stable magnetic properties at high temperatures (to 350 degree )
. Excellent corrosion resistance capability, no coating is needed for surface protection
Attributes of Samarium Cobalt
. High resistance to demagnetization
. High energy (magnetic strength is strong for its size)
. Good temperature stability
. Expensive material (cobalt is market price sensitive)
Process Flow:
Raw material-----Mixing-----Melting-----Power-----Pressing-----Sintering----Magnetic -----Inspection-----Cutting and Grinding-----Inspection-----Packing and Shipping
