NdFeB – Processing Sintered Neodymium Magnets N38EH Block Super Strength Ndfeb Magnets
The production of NdFeB magnets begins with melting of the alloy and the careful addition of special elements to enhance the particular properties required of the finished magnet.
The ingot is then crushed and milled to a fine powder under protective atmosphere. Depending on the type of magnet being produced, the powder is either isostatically pressed into a block or die pressed to a particular component shape. During the compaction it is important to apply a large alignment field to orientate the particles for the preferred magnetic direction.
The compacts are transferred to furnaces which operate under high vacuum. The sintering process is completed by a separate heat treatment stage to develop the magnetic properties.
Finishing of the magnets is accomplished by grinding to the required tolerance or slicing a large block into the desired shape.

neodymium-rectangle-transThe relatively small and difficult to access ore deposits containing rare earth elements contributed to the initial naming of the seventeen elements. The term “earths” simply refers to naturally occurring mineral deposits. The historical scarcity of these elements made its namesake inevitable. Currently,
China meets approximately 95% of global demand for rare earths – mining and refining around 100,000 metric tons of rare earths a year. The United States,

Afghanistan, Australia, and Japan also have significant rare earths reserves.
The second explanation for rare earth elements being designated “rare earth” was due to difficulty in both the mining and refining processes, which was typically done by crystallization. The term “rare” is historically synonymous with “difficult.” Because their mining and refining processes were not simple, some experts suggest the term “rare earth” was applied to these seventeen elements as a result.
