Samarium Cobalt Magnets

A reliable source for Magnet Assemblies information and leading Magnet Assemblies Companies & Manufacturers.

Often found in applications where high temperatures are a factor, these incredibly strong magnets are second only to neodymium magnets in terms of temperature limits in magnets. In order to know if a rare earth magnet is right for your applications, we encourage you to consult a samarium cobalt magnet manufacturer who will assess your needs and requirements based on your application in order to determine the right magnetic solution for you.

The magnetic force within samarium cobalt magnets is rather strong, as is the case with most rare earth magnets. These magnets are made from a combination of materials and commonly have around 25% to 36% samarium in them. The other materials are mostly two different types of alloys with the first being known as series 1:5 and the second is known as series 1:7.

Samarium Magnet Samarium Cobalt Magnets - Master Magnetics, Inc.

The series 1:5 magnets have a magnetic strength rating of 16 to 25 MGOe, while series 1:7 has a magnetic strength rating of 20 to 32 MGOe. The way magnetic strength is measured is through the energy in products with units of megagauss-oersteds or MGOe. Samarium cobalt magnets are manufactured through the use of sintering and a series of pressing processes.

The sintering process works to fuse together the tiny particles in the samarium cobalt material while the pressing process can be accomplished in two ways. The first method uses die pressing where pressure is applied from one direction, and the second method uses isostatic pressing where pressure is applied in all directions within a rubber mold.

There are a number of different ways to customize a samarium cobalt magnet. For example, the magnet's Curie temperature, certain tolerances, and even the magnetic strength can all be modified to fit within the manufacturing process to fit the specific needs of your applications. This is why it is so important to find a trusted, experienced samarium cobalt manufacturer in order to receive a custom solution that is manufactured with your application in mind.
