SmCo Arc Magnets

The rare earth arc magnets on this page are made from the rare earth magnetic material samarium and cobalt. Samarium cobalt arc magnet is the second strong magnetic material behind neodymium,and widely used because they are much more resistant to corrosion and have higher maximum operating temperatures. Beilun Meank supplys rare earth samarium cobalt (SmCo) arc magnets for motors where neodymium arc magnets can not work. Some of SmCo arc magnets are finished with a triple coating of nickel, copper and nickel when they are used in acidic and high moisture environment.

Just let us know what sizes of  samarium cobalt (SmCo) arc magnets you are looking for, the lowest and fairest price is possible for large quantity.

Care required for handling Samarium Cobalt arc Magnets:

Rare earth SmCo arc magnets are very strong and brittle, appropriate handling and packing  required to ensure safety and prevent damage.

The brittle nature of the alloy can lead to flying chips if the magnets are allowed to impact each other or a solid surface. Most receiving departments are not familiar with the strength of Samarium Cobalt magnets and this can result in injury or broken parts. All personnel that may come in contact with this alloy should be made aware of the dangers of handling these arc magnets.  Larger SmCo arc magnets can become a pinching hazard if caution is not exercised. We remind all customers to  handle SmCo arc magnets with care.

Available Grades of Rare Earth Samarium Cobalt Arc Magnets:

Various grades of Samarium Cobalt(SmCo) arc magnets are available for industrial and commercial applications. The magnetic energy of SmCo arc magnet range from 16 to 32 MGOe. The grade range allow for balancing cost, magnetic performance, and operational temperature resistance.

There are two main types of arc Samarium Cobalt (SmCo) rare earth magnet alloy.  The older type, typically denoted as (1-5) having one Samarium atom per 5 Cobalt atoms, and the newer Samarium Cobalt magnet alloy, typically denoted as (2-17), having an atomic ratio of two Samarium atoms to 17 Cobalt atoms.
