Production Capacity: 80TON/MONTH
Delivery Date: 7-30days
Type: Permanent
Brand Name: rainbow magnet
Means of Transport: Ocean,Air;experess
Packing: standard air cartons or sea...
Application: Speaker Magnet
Composite: Rare Earth Magnet

Metal samarium, cobalt, copper, iron, zirconium, according percentage to melting, grinding, profiling, sintering, aging, and make of various grades,

Samarium cobalt magnets are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.
According the composition, we divide two of SMCO: Sm2CO17 and SmCo5

the picture shows the ring is Sm2Co17.

The (BH)max between 20-32, the maximum operating temperature can bereached 350 °C, the 2:17 has a low temperature coefficient (-0.02% / ℃) and good corrosion resistance, magnetic properties ismore than NdFeB magnets when in high working temperatures,
Sm2co17: not only has a high intrinsic saturation magnetic induction, but also good anti-oxidation.
The Curie temperature is high to 840-870 degrees, higher than Smco5.
The disadvantage is that the process is complex with high costs.
