SmCo Disc Magnets

Samarium cobalt(SmCo) disc magnets are made of an alloy of samarium and cobalt. They have strong magnetic strength like as neodymium disc magnets.The reason why SmCo disc magnets are widely used is their ability to maintain magnetic force. For example, SmCo disc magnets can work in applications that operate at extremely high or low temperatures.

If you need rare earth disc magnets that are not easily corroded or oxidized, then samarium-cobalt(SmCo) magnets will be available. Protective coating is usaually not  needed for SmCo disc magnets. However, we recommend that you use them with care because they are fragile and easy to crack or chip. We provide various customized grades and sizes of smco magnets for sale.Contact us now for quotation!

SmCo disc magnets are very strong and brittle, appropriate handling and packing  required for handling SmCo disc magnets  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.  Big SmCo disc magnets can become a pinching hazard if caution is not exercised. We remind all customers to  handle SmCo disc magnets with care.

Available Grades of Rare Earth Samarium Cobalt Disc Magnets

Various grades of Samarium Cobalt(SmCo) disc magnets are available for industrial and commercial applications. The magnetic energy of SmCo disc 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 disc shape 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. Both rare earth SmCo5 and Sm2Co17 disc magnets can be supplied by Beilun Meank
