SmCo Bar Magnets

The long rare earth SmCo block magnets are called as SmCo bar magnets.Rare Earth samarium cobalt (SmCo) block bar magnets can be used in high temperature environment or applications with demagnetization potential.SmCo bar magnets can be custom machined in different ways and can be magnetized in a specified direction. But the direction of magnetization must be fixed during the manufacturing process and cannot be changed when the magnet is made,which is the same as neodymium bar magnets.

Appropriate handling and packing required for SmCo block bar 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 bar 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 bar magnets can become a pinching hazard if caution is not exercised. We remind all customers to  handle SmCo bar magnets with care.

Available Grades of Rare Earth Samarium Cobalt Bar Magnets:

Various grades of Samarium Cobalt(SmCo) bar magnets are available for industrial and commercial applications. The magnetic energy of SmCo block bar 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  Samarium Cobalt (SmCo) rare earth bar magnet alloy.  The older type, typically denoted as (1-5) having one Samarium atom per 5 Cobalt atoms--SmCo5 magnets, and the newer Samarium Cobalt magnet alloy, typically denoted as (2-17), having an atomic ratio of two Samarium atoms to 17 Cobalt atoms--Sm2Co17 magnets.
