Coatings for Neodymium Magnets

Coatings for Neodymium Magnets

Nearly every neodymium magnet will be plated or coated and, as the most powerful permanent magnet available, they are used in many different applications. However, they possess physical characteristics that require them to be plated or coated in order to protect them from damage. In their raw form, neodymium magnets are quite brittle, and as…

The History of Neodymium Magnets

History of Neodymium Magnets banner

The origin of the neodymium magnets dates back to 1885 when Carl Auer von Welsbach, an Austrian scientist and inventor, separated didymium into the new separate elements neodidymium (“new didymium”) and praseodidymium (“green didymium”).  In time, the element names would change to neodymium and praseodymium. Neodymium (Nd) is the fourth member of the lanthanide ‘rare-earth…

Rare Earth Magnets in Electric Vehicle Motors

Electric Vehicle Plugged in and charging

The global move towards the electrification of vehicles continues to gather momentum.  In 2010, the number of electric cars on the world’s roads reached 7.2 million, of which 46% were in China (iea.org/reports/global-ev-outlook-2020).  By 2030, the number of electric cars is expected to swell to 250 million, a massive growth in a relatively short time.…

Explaining Neodymium Magnet Strength

Neodymium Magnet Strength

Neodymium Rare Earth Magnets are the strongest commercially available permanent magnets in the world.  Originally invented by General Motors and Sumitomo Special Metals in the early 1980s, Neodymium Magnets are a key component in mobile phones, computers, wind turbines, and modern cars.  The list of applications is nearly endless. As the name suggests, the prime…

Magnet Comparison: Neodymium and Samarium Cobalt Rare Earth Magnets

Battle of the Rare Earth Magnets

Neodymium Iron Boron NdFeB (i.e. Neodymium) and Samarium Cobalt SmCo are both ultra-strong rare-earth permanent magnets.  Both are brittle in nature and subject to catastrophic damage if subject to severe impact (i.e. dropping).  However, that is where the similarity ends and, when selecting a magnet material for a specific application, our design engineers assess each…
