Neodymium Magnets

Neodymium permanent 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. Thin neodymium magnets,
mini 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 neodymium magnet suppliers in China, RiSheng has various types of
neodymium magnets for sale, in our online shops and physical stores, with
competitive price per kg, very cost effective. In terms of the size, our
factory supplies not only the small series— paper thin, micro, tiny, mini, but
also the big ones—large, huge, giant monster. Considering practical
applications, we provide customized neodymium magnets. They are of different
shapes: arc, rod, bar, ball, ring, disc, flat, block, sphere, eclipse, curved,
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, some
can be made super strong, adhesive, waterproof. For the convinience of our
customers, Risheng has already prepared relevant pdf files and videos about
neodymium magnets. Contact us immediately, get cheaper price with best service.

Grades Of Neodymium Magnets
We can manufacture and supply all the grades from energy product 35MGOe to
52MGoe and from N series to AH series.

Demagnetization Curves Of Neodymium Magnets
As one of the most professional magnet manufacturers, we list the performance
of the highest grades with different series when demagnetization.

Physical Properties Of Neodymium Magnets
A few main physical properties are listed, like density, curie temperature,
etc.

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.

Manufacturing Method Of Neodymium Magnets
Neodymium magnets are made by a sophisticated process using very advanced
metallurgical methods, the main process is Rare earth raw materials - Quick
curing - Strip casting - Hydrogen decrepitation - Milling - Pressing -
Sintering - BH curve testing - Machining - Plating - Magnetizing - Packaging.

Applications Of Neodymium Magnets
Neodymium magnets are widely used for industrial, technical, commercial, and
consumer applications, the most common applications are motors/generators,
sensors, audio equipment, holding/lifting systems, magnetic bearings, hard disc
drives, levitation devices, magnetically coupled pumps, medical devices,
magnetic separators, packaging closures, commercial signage/display.
