MAGNETIC BALLS / SPHERE MAGNETS - NEODYMIUM (NDFEB) RARE EARTH 

These precision Neodymium Sphere Magnets are available in 2.5mm to 50mm diameter. They are commonly used in sculptures, artistic displays and experiments. The power of these magnets should not be underestimated; there is a risk that these magnets will chip and break if they are allowed to slam together. Because of this they are not suitable for children and should not be bought as toys.

Neodymium Magnetic Balls, Sphere Magnets, Neodymium (Rare Earth)

Magnetic neodymium spheres have both practical uses and are just plain fun. These ball magnets are used in many chemistry and physics classes, make great “worry beads” and are great to have around.
These magnetic spheres are made of neodymium magnet, a magnetic material developed in the 1980s and updated many time since. These magnetic ball products are protected by a shinning and nice looking Ni-Cu-Ni coatings, so to protect your ball magnets from rusting. Your magnetic balls maintain their strong magnetic pull up to 80 celsius.

Neodym Magnets: the strongest magnets in the world  

We offers best priced Neodymium magnets globally to all industries, including Automotive, Aerospace, Military, Advertising, Design House, Electronic and Academic/R&D. Please inquire for custom Neodymium magnets or magnetic assembly.
Neodymium is the strongest available magnet alloy at up to 52MGOe. The use of Neodymium results in smaller, more cost-effective magnet solutions replacing older materials like Alnico and Ceramic in many applications. We can help optimize performance and cost with Neo magnets in grades from 33 to 52MGOe and operating temperatures up to 230°C/446°F.
(NdFeB) Neodymium, a rare earth magnet, is made up of Neodymium Iron and Boron and is moderate in price. A neodymium iron boron magnet is usually plated or coated (Examples: Nickel Plated, Epoxy Coated, Parylene Coated). Neodymium permanent magnets usually offer the best value when comparing price and performance. Stock Neodymium magnets are available in large quantities and dimensions.

Rare Earth Neodymium NdFeB

We provide a range of high magnetic strength Rare Earth Neodymium magnets including Disc magnets, Deep Pot magnets, Shallow Pot Neodymium and Round flat neodymium magnets, perfect for low profile applications, or high power holding applications.

Due to their high strength and low cost, neodymium magnets revolutionized magnetic products. These magnets are the strongest developed thus far. Because neodymium magnets are between seven and fourteen times stronger than ceramic magnets they are sometimes called super strong or powerful magnets. 

  • Neodymium NdFeB magnets are, size for size, the strongest type of any magnet material that is commercially available.
  • Neodymium NdFeB magnets are often the ideal first choice for many applications because they offer a maximum performance from the smallest magnet volume.
  • Neodymium NdFeB should always be coated to guard against the risk of corrosion – NiCuNi, Zinc, NiCuEpoxy and Gold are popular finishes.

Neodymium NdFeB magnets and their application!

We sell custom Neodymium NdFeB magnets and custom magnetic assemblies so we can help you find the best fit for your project. Some of the common applications of the rare earth magnets are:

  • Motors and Generators
  • Meters
  • Automotive (clamps, sensors)
  • Aerospace
  • Separation (rods, grids, etc) – 10-12kG (22-26lbs) systems
  • High performance magnetic clamps and pot magnets
  • They are used in computer hard drives.
  • Rare earth magnets also find their utility in high-end speakers.

  • Process of Making Rare Earth Magnets

    The rare earth magnets are made by using different process involving various stages. The popular stages of the production of rare earth magnets are:
  • The first stage is the manufacture of rare earth element alloys.
  • The metal alloy is then finely powdered.
  • The next step involved is pressing of powder either isostatically or pressing through die process.
  • The particles so pressed are oriented.
  • Sintering of the element is done accordingly.
  • The shapes are then sliced into desired shapes and sizes.
  • The coating is done thereafter.

After finishing the above tasks, the finished shapes are magnetized.
