Materials
  The production of NdFeB and SmCo 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.
