Permanent Sintered Square Neodymium Magnets
Neodymium magnets are a combination of Neodymium (Nd), Iron (Fe) and Boron (B), and are also referred to as NdFeB or Neo. These are the strongest of the rare earth magnets and used in virtually every industry. Rare Earth Neodymium Square magnets allow a uniform magnetic field across the square magnet face and can be made in any thickness. Applications include sensors, consumer products, and holding applications.
Products description
20mm x 20mm x 2mm thick.
+/-0.1mm tolerance.
Each magnet's north and south pole are on opposite 20mm x 20mm square faces.
Each magnet can support a steel weight of up to 7.8kg vertically from the magnetic face when in flush contact with a mild steel surface.
Excellent resistance to demagnetisation.
Each magnet is coated with three layers of nickel, copper and nickel to improve corrosion resistance and provide a smooth and clean finish.
Key Advantages of Neodymium Magnet:
Neodymium Magnet are the most powerful commercially produced magnets.
Neodymium Magnet have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
Neodymium Magnet can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
Neodymium Magnet has very high strength.
Relatively low cost.
Compared to Alnico and SmCo magnets, relatively easy to machine.
