Neodymium Magnets


Neodymium magnets (also called NdFeB permanent magnets, Neo magnets) are consisted of Nd (neodymium), Fe (Ferrum), B (boron), and other elements like Dy (dysprosium) and Ti (Titanium). As part of the permanent magnet family, they are the latest generation of rare earth magnets. Neodymium magnets are extremely super strong magnets commercially available in the world, their pull force are quite strong compared to their own size, they have high magnetic remanence, high energy product and relative good coercive, due to these advantages, they are the most widely used magnets today.


As a reputable neodymium magnet manufacturer in China, RiSheng has various types of powerful magnets for sale, in our online shops and physical stores, with competitive prices per kg, very cost-effective. In terms of the size, our factory supplies not only the small neodymium magnets series— paper-thin neodymium magnets, micro, tiny neodymium magnets, mini neodymium magnets but also the big ones—large, huge neodymium magnets, giant monster neodymium magnet. Considering practical applications, we provide customized neodymium magnets. They are of different shapes: arc, rod, bar, ball, ring, disc, flat, block, sphere, eclipse, curved neodymium magnets, bonded, rectangular, cylindrical, with countersunk holes; and are for different purposes and industrial uses: for cutting, drilling, grinding, machining, for therapy, water meter, etc. Some of them can be sintered, silicone coated neodymium magnets, some can be made super strong, adhesive, waterproof. For the convenience of our customers, Risheng has already prepared relevant PDF files and videos about neodymium magnets. Contact us immediately, get a cheaper price with the best service.

Sizes & Tolerance of Neodymium Magnets

We can produce different shapes, like a disc, cylinder, ring, arc segment, and custom complicated shapes, a wide range of sizes are possible with a few limits.

The standard tolerances are generally +/-0.1mm, while slightly varies depending on how big the size is.

Magnetization of Neodymium Magnets

All Neodymium magnets are anisotropic and oriented with a preferred direction during production, they can only be magnetized thru the oriented direction. Disc/cylinder/ring magnets are axially or diametrically magnetized, block magnets are magnetized along one side of three sides, arc segment magnets are generally diametrically magnetized.

Surface Coatings of Neodymium Magnets

The corrosion resistance of Neodymium magnets is considered very poor, a surface coating will be necessary, the most common coatings are NiCuNi, Zn, Black Epoxy, Teflon/PTFE, Rubber/Plastic.
