Super neodymium magnets with high magnetic properties
NdFeB magnets (Neo, NdFeB or NIB magnets) are the strongest type of permanent magnet commercially available, outperforming Alnico and ceramic (ferrite) magnets. The size of the sintered NdFeB magnets provides an extremely high energy product, they have a high remanence and a much higher coercivity than other permanent magnets. They are available in a variety of shapes, sizes and grades at relatively low prices.
Neodymium magnets (also known as "NdFeB", "Neo" or "NIB" magnets) are super neodymium magnets made from an alloy of neodymium, iron and boron. As part of the family of rare earth magnets, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low cost, they are the preferred choice for many consumer, commercial, industrial and technical applications.
Applications - Neodymium magnets are used in a variety of applications and are ideally suited for small parts and assemblies. Common applications range from crafts and model making projects to high performance motors, medical instruments, audio components, POP displays, scientific projects, home improvement projects, hanging artwork and more.

Why neodymium magnets are super neodymium magnets
Many of you may be asking yourselves: Why are neodymium magnets super magnets? And: Aren't cheap ferrite magnets enough for my project? The special NdFeB combination (neodymium iron boron) produces a high adhesion force even in small magnets. It is no coincidence that neodymium magnets are also known as high-performance magnets. Compared to NdFeB magnets, ferrite magnets of the same volume are much weaker. This is why neodymium magnets are called super magnets.
If you need small and light magnets or large and super neodymium magnets, we recommend that you buy super magnets. In the category of our online shop you can find the perfect magnet for your project, from mini magnets to super neodymium magnets. neodymium magnets are slightly more expensive than ordinary ferrite magnets because neodymium is a rare earth metal. For this reason, super magnets are also known as rare earth magnets.
When to use ferrite super neodymium magnets.
Exposure to temperatures in excess of 80 °C
For outdoor use we also carry some rubberised super magnets. Also available in our online shop: self-adhesive neodymium magnets, e.g. for paper and cardboard products, name tags and clasps for crafts.
There are more than 10 coating methods and coating is high temperature resistant, solvent resistant, and multi-colored. The common ways include Nickel-Copper-Nickel (Ni-Cu-Ni), Nickel (Ni), Tin (Sn), Zinc (Zn), Gold (Au), Expoxy, etc. Otherwise, magnets with high temperature resistance can be coated with rubber and silicon.
The minimum thickness of ring magnet that AH Magnet makes is 1.5mm.The magnets has wide applicable temperature range from 80℃ to 230℃ and long service life.Highly stability under difficult environment conditions, high resistance to demagnetization, corrosion and oxidation.
Although NdFeB magnet is a kind of hard and brittle material, we can customize some complex shapes according to customers requirements. We have produced some complex shapes such as different heads, convex, concave, slotted, side punched, cut corners, non-semi-circular and countersunk magnet.
Linear Halbach Arrays: To be used for brushless AC motor, voice coils, high-tech applications such as particle accelerators and free-electron lasers. Halbach Cylinder: Applied for magnetic couplings, brushless AC motors and high field cylinders. Both brushless motors and coupling devices use multipole field arrangements.

Facts about super neodymium magnets
The neodymium-iron-boron alloy (NdFeB) was developed in the early 1980s. It is used to manufacture neodymium magnets and it is still on the market today as super neodymium magnets.
Many super neodymium magnets can be used up to 80 degrees. If they are heated above that temperature, they lose their magnetism. In our range of super neodymium magnets you can also find high temperature block magnets. These neodymium magnets can withstand temperatures of up to 150 degrees.
Selling super neodymium magnets
We carry neodymium magnets ranging from N42 to the strongest neodymium magnet widely available - N52 (higher grades of neodymium magnets are available, but they are much more expensive and are usually only available on special order). When comparing different suppliers of rare earth magnets, make sure you are comparing similar grades, as many come with lower grades, such as N35.
In addition to a wide range of grades, sizes and shapes, we also offer high temperature super neodymium magnets. these are listed in a separate sub-category called "high temperature neodymium magnets". The rating of these will include a code at the end to indicate them - for example N42SH.
AH has a large stock of licensed super neodymium magnets available for immediate purchase online at bulk discount prices. We offer neodymium discs, rectangular or square neodymium blocks, bars, rings and rods in a variety of sizes, premium grades and finishes. Not all of our neodymium magnets are shown on this site, so if you don't see what you are looking for, please contact us today.
