Sintered Magnet: is one of the high performance rare earth permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as their main ingredients and is susceptible to demagnetization when exposed to elevated temperatures. There are many grades which can withstand high temperatures, but several factors will dictate the performance of the Neodymium magnet. There are Sintered NdFeB, Sintered AlNiCo, Sintered SmCo and Sintered Ferrite.

NdFeB magnets, have the characteristics of :
    Super strong Br Resident induction.Excellent demagnetization resistance capability.
      Good Price relative to its high magnetic properties.
      Coating is needed for NdFeB
      Surface Treatment Method: Type Information
      Metallic Zinc, Nickel, Nickel+Nickel, Copper+Nickel, Nickel+Copper+Nickel,
      Gold, Organic Epoxy, Nickel+Epoxy coating
