Electroplating is another term for coating. Plating or coatings are applied to raw neodymium magnets to prevent corrosion and demagnetization. The most common plating is a layer of nickel, followed by a later layer of copper and another layer of nickel. These different coatings, for tailor-made applications, are offered:

  • Rubber
  • Nickel (Ni)
  • Epoxy
  • Zinc (Zn)
  • Gold (Au)
  • Can (Sn)
  • Titanium (Ti)
  • Titanium nitride (TiN)
  • Parylene C
  • Everlube
  • Chrome
  • Polytetrafluoroethylene (PTFE, also known as Teflon Ni-Cu-Ni plus epoxy)
  • Nickel-copper-nickel, plus rubber
  • Zinc, plus rubber
  • Nickel-copper-nickel, plus parylene
  • Nickel-copper-nickel, plus PTFE
  • Tin, plus parylene
  • Zinc Chromate
  • Phosphate passivation
