Neodymium is a chemical element with the symbol Nd and atomic number 60. It is the fourth member of the lanthanide series and is considered to be one of the rare-earth metals. It is a hard, slightly malleable, silvery metal that quickly tarnishes in air and moisture.  When oxidized, neodymium reacts quickly producing pink, purple/blue and yellow compounds in the +2, +3 and +4 oxidation states.    It is generally regarded as having one of the most complex spectra of the elements. Neodymium alloys are used to make high-strength neodymium magnets—a type of powerful permanent magnet.  These magnets are widely used in products like microphones, professional loudspeakers, in-ear headphones, high-performance hobby DC electric motors, and computer hard disks, where low magnet mass (or volume) or strong magnetic fields are required.  Larger neodymium magnets are used in electric motors with a high power-to-weight ratio (e.g., in hybrid cars) and generators (e.g., aircraft and wind turbine electric generators)ATT provides Neodymium and compounds at a competitive price, including Neodymium Acetate, Neodymium Carbonate, Neodymium Chloride, Neodymium Fluoride, Neodymium Hydroxide, Neodymium Metal, Neodymium Nitrate, Neodymium Oxalate, Neodymium Oxide, Neodymium Sulfate,neodymium magnets
