Neodymium Magnets

Neodymium magnets are composed of neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny
corrosion resistant finish.

Neodymium magnets are the strongest permanent magnet, the magnetic properties far exceed other permanent magnet materials.

Their high magnetic strength, resistance to demagnetization, low cost and versatility make them widely used in many fields, such as motors, sensors, microphones, wind turbines, wind generators, ect.

Grades of Neodymium Magnet

Neodymium magnets are all graded according to the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52.

Magnet Coating

Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. There are a variety of options for coatings, but nickel is the most common and usually preferred. Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel plated magnets. Some other options for coating are zinc, tin, copper, epoxy, silver and gold. Our gold plated magnets are actually quadruple plated with nickel, copper, nickel and a top coating of gold.
