Customized Coated Samarium Cobalt Magnet for National Defense Application

Product Description:

These magnets are characterized by high magnetism, and are also resistant to both rust and high temperature.
These magnets represent the highest magnetic energy product after neodymium magnets. They are also highly
corrosion-resistant without being rustproofed and offer excellent temperature characteristics as well. These are
rare-earth magnets resistant to high temperature.
These sintered products consist mainly of samarium (Sm) and cobalt (Co), and are available with two kinds of material:
1-5 series and 2-17 series. The 1-5 series has high magnetic coercive force (Hcj), but is easy to magnetize and adjust
magnetism. Magnets of this series also exhibit relatively stable performance under changing temperature. The 2-17
series has high magnetism and offers excellent temperature stability in magnetic characteristics as well.
Samarium-cobalt magnets are relatively low in mechanical strength. Caution should therefore be exercised in handling
these magnets to prevent chipping and cracking.

Samarium Cobalt Magnets
Samarium cobalt magnets (SmCo) 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.

Manufacturing - In general, the elements are melted together and milled into a powder that is dry-pressed
shape in the presence of a magnetic field. The material is then sintered, aged, ground to dimension, magnetized and tested. They are called “rare earth” magnets because the elements of samarium cobalt
classified as such in the lanthanides section of Periodic Table of the Elements.

Attributes of Samarium Cobalt
High resistance to demagnetization
High energy (magnetic strength is strong for its size)
Good temperature stability
Pricing for samarium cobalt is market sensitive
