Product Description
ring Smco magnet
Applications:
Bonded SmCo magnetic energy parameters
Compare of bonded permanent magnetic magnet
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
According the process, we divide to sintered Smco and bonded Smco
Bonded SmCo
Features:
Bonded Smco magnet have high accuracy. Not only have vary shape
Specifications, but also have strong corrosion resistance, and high temperature
Stability.The surface is without treatment;
Applications:
²Computers and office automation: HDD, CD, DVD-ROM
