Samarium cobalt magnet is a type of permanent magnet. They have lower MGO values, between 24MGOe-28MGOe, and operate at temperatures up to 575 degrees Fahrenheit. Samarium cobalt (SmCo) magnets and neodymium iron boron (NdFeB) magnets are known as rare earth magnets.

Samarium Cobalt (SmCo) magnets are available in different grades with a wide range of properties and application requirements. They are anisotropic and can only be magnetized in the direction of orientation.

It is brittle and machined before magnetization and we are able to manufacture Samarium Cobalt magnets to our customers’ specifications.

Edgetech Industries’ Magnetism division offers Samarium Cobalt magnets including Samarium Cobalt Block Magnets, Samarium Cobalt Ring Magnets, Samarium Cobalt Disk Magnets, Samarium Cobalt Cylindrical Magnets, and other Samarium Cobalt Magnets.

Samarium cobalt magnets are available in sintered and bonded forms. Samarium cobalt magnets have better corrosion resistance than neodymium magnets. Therefore, SmCo magnets generally do not require corrosion-resistant coatings.

Their mechanical properties are very weak, but their magnetic properties are powerful. They must be handled carefully to avoid damage and injury to those handling the magnets. Receiving and assembly personnel should be warned of the dangers of handling magnetized rare earth magnets (samarium cobalt and neodymium magnets).
