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.
FAQ
Q)How material grade and magnet dimensions(L x W x H) affects the Gauss Level of magnets?
A)Same magnet size, Higher grade with higher gauss
Same magnet grade, same surface area, the thicker, the higher gauss
Same thickness, same thickness, larger surface area with lower gauss
Q) What are neodymium magnets?
A) Neodymium magnets are a member of the rare earth family and are currently the strongest permanent magnets in the world!
They are composed of neodymium, iron and boron (NdFeb)
Q: What does pulling force mean?
A: Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid
magnetic surface, such as a steel plate.
Q: Do I have to worry about temperature with neodymium magnets?
A: Yes. They are sensitive to heat so do not heat them above 175°F (80°C) If you do, they will begin to lose their magnetic
strength. This normally applies only to industrial usage of ;heating the magnets, normal application will not affect the
strength of the magnets.
Q: If I stack two neodymium magnets together, does their strength double?
A: No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined
pulling force of 90 lbs when stacked together.
Q: Do neodymium magnets lose strength over time?
A:No. They do not naturally lose any appreciable strength and will last your lifetime!
