Neodymium Magnets

What Are Neodymium Magnets?

Neodymium magnets are super permanent magnets. It is commercially available. They are more expensive than other magnets since it made of rear earth. They have many advantages that make them such desirable materials in so many industries. They’re stronger, smaller and more versatile than any other commonly used magnet.

Shapes

Customers get a large variety of shapes when they need to choose from different neodymium magnets in shape, strength, and size. The neodymium magnets are popular and versatile for their unique shapes and magnetic strength. Neodymium magnets are manufactured from the boron, iron, and neodymium and the mixture of these three elements transforms these magnets into the strongest and the most powerful available magnets on the planet Earth.

Different applications require different shapes of neodymium magnets. Design magnets serve the purpose of producing something creative and artistic and sometimes you need small, simple, and powerful magnets. But now, you do not need to search out the market for different shapes because Osenc can provide you with a variety of shapes. Osenc manufactures neodymium magnets in disk countersunk, squares, spheres, rings, square countersunks, disks or rod, etc.

Coatings

All the above shapes of magnets come in different coatings because the coating prevents rusting. The most common coating for neodymium magnets is nickel-copper-nickel or copper-nickel plating. A good choice for neodymium magnets is Zn coating because of its attractive price. visit here to know more about the neodymium magnet coating.

Size

When buying neodymium magnets, make sure that you are choosing the size of magnet that fulfill your need. Osenc can manufacture the magnet as small as 0.2mm and as large as 200mm.

Grades

What does it mean by N35, N38, N42,….?

Neodymium magnets are actually graded by the material from which they are made of. As a rule, the higher grade (a number following ‘N’), the stronger the magnet will be. Currently, the highest grade of neodymium magnets is N56. But it is not the most widely used. The highest grade that is most widely used in the market is N52.

Directions Of Magnetization

Neodymium magnets have their own respective corresponding magnetization directions according to their sizes and shapes. For example cylinder and the disc magnets can be diametrically and axially magnetized and for the neodymium sphere magnets, only axial magnetization is present.
