Rare Earth Magnets

Powerful solutions for a wide range of applications

Overview

Rare earth magnets are magnets made from alloys of rare earth elements, including neodymium iron boron or samarium cobalt. They are currently the strongest type of permanent magnets, producing significantly stronger magnetic fields than other types of magnets like ceramic or alnico magnets. This quality has led to them replacing alnico and ferrite magnets in many applications, including head actuators for computer hard disks, magnetic resonance imaging (MRI) systems, loudspeakers and headphones, motors, and more. At Adams Magnetic Products, we’ve engineered and manufactured magnetic products for over 70 years. This extensive experience provides us with the knowledge and skills needed to deliver magnet solutions for nearly any customer application. Below, we highlight the rare earth magnet products we offer and outline some of their typical applications.

When you need magnet assemblies and permanent magnets that perform optimally over the long-term in the toughest conditions for aerospace, military, and defense applications, Adams delivers. Let us employ our knowledge of the physical and mechanical properties of magnetic materials from the earliest stages of your design to suggest the most effective, lightest, and cost-effective options.

Neodymium Magnets

Our technical experts are ready to answer your questions and address your magnetic needs. Whether it’s selecting a magnet for a particular application and environment, choosing the most cost-effective material, or reviewing options from what is available in the market, we are here to help with:
• Highest power-to-weight ratio
• High resistance to demagnetization
• Low machinability (no conventional drilling, turning, milling)
• Suitability for magnetization in any direction and multiple pole magnetization

In many cases, neodymium magnets are a less brittle and more economical alternative to samarium cobalt magnets. However, they are only suitable for certain applications because of their sensitivity to high temperatures and susceptibility to oxidation. We offer the following types of neodymium magnets:
• Neodymium block magnets
• Neodymium disc magnets
• Neodymium ring magnets
• TabMAG® neodymium magnets with adhesive

Samarium Cobalt Magnets

Like neodymium iron boron, samarium cobalt is a rare earth material available in both sintered and bonded forms.

The two materials share many attributes, including High Br, high Hc, relatively high BHmax (approximately 18–33 MGOe), high resistance to demagnetization, low machinability, and suitability for multiple pole magnetization given the proper magnetizing fixture is available. However, compared to neodymium iron boron, samarium cobalt offers greater corrosion resistance and thermal stability, making it better suited for applications involving corrosive chemicals or extreme temperatures.

We offer the following types of samarium cobalt magnets:
• Samarium cobalt block magnets
• Samarium cobalt disc and ring magnets
