Product details
Rare earth permanent samarium Cobalt smco Ring Magnets
Samarium Cobalt (or SmCo) magnets are strong permanent magnets made of an alloy of samarium and cobalt. They are known for their high magnetic strength, exceptional temperature resistance, and reliable performance without oxidation protection. As a result, they are more suitable for certain applications than Neodymium magnets.

Production information:
Name Rare earth Permanent Samarium Magnet SmCo
Grade SmCo1:5 and SmCo2:17
Shape Disc, Round, Bar, Block, Arc, Ring, etc. Customized according to customer's requirement
Sizes Customized according to customer's requirement
Tolerance Standard tolerance, according to customer's requirement
Application SmCo is used in pump couplings, sensors, and servomotors; where the magnet is required to perform at elevated temperatures or across a wide temperature range, and in corrosive environments.
