Rare Earths

Rare Earth elements, largely unknown to the majority of the general public, have become national news in the past decade. The magnet industry has used samarium, neodymium, dysprosium and other rare earths for decades as they are a very important ingredient in magnet design. Many of these magnets have enabled new technologies and are also critical to green initiatives such as wind turbines and hybrid cars.

Arnold has a “mine to magnet” solution for its production of RECOMA® samarium cobalt magnets.

Most of the material produced in our Lupfig facility stays in Europe, however, we also ship SmCo block from Lupfig to Rochester, NY for fabrication into magnets for industrial and defense use.

We have a relationship with a rare earth mine in China to provide either SmCo alloy or samarium for our China manufacturing facility as well as our other facilities around the world. The magnets produced in China generally stay in the Asia Pacific, but we do import NeFeB and injection molded magnets for select customers. For projects requiring DFARS/NDAA compliant neo magnets, contact your Arnold Representative.

We do not believe that any other Western supplier has such a robust supply chain for its SmCo magnet production.

Many of our customers are worried about the future supply of SmCo magnets. We are highly confident that our supply chain will allow us an uninterrupted source of raw materials to comply with the relationships and agreements that we have in place to produce the magnets needed. If requested, we are also able to stock material for our customers

Samarium Cobalt as the Rare Earth Magnet Material of Choice

Samarium cobalt magnets are a great choice when designing motors, generators or sensing systems. Unlike neodymium and even more importantly dysprosium which is used to give neodymium iron boron magnets higher temperature performance, there is an excess of samarium in the rare earth supply chain. We estimate that SmCo magnet usage could almost triple before the supply chain was constrained.
