SmCo Block Magnets

Samarium cobalt(SmCo) block magnets （also known as rare earth block magnets）are made of an alloy of samarium and cobalt,which also have strong magnetic force like as neodymium block magnets. Because of their ability to maintain magnetic force,samarium cobalt(SmCo) block magnets are better choice than neodymium block magnets for working in extremely high temperatures.The SmCo magnet blocks that have the same size for length,width and thickness are also called SmCo cube magnets.

If you need rust resistant rare earth block magnets, then samarium-cobalt(SmCo) magnets will be your first choice. Surface treatment is not needed for SmCo block magnets. However, but hey are fragile and easy to crack or chip, we recommend that you use them with care. We provide various customized grades and sizes of SmCo block magnets.Contact us now for quotation!

Care required for handling Samarium Cobalt Block Magnets:

SmCo block 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 magnets.  Larger SmCo magnet blocks can become a pinching hazard if caution is not exercised. We remind all customers to  handle block SmCo magnets with care.

Available Grades of Rare Earth Samarium Cobalt Block Magnets:

Various grades of Samarium Cobalt(SmCo) block magnets are available for industrial and commercial applications. The magnetic energy of  block SmCo 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 block Samarium Cobalt (SmC) 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.
