Big Neodymium Magnets are used in a wide range of items, such as household electronics, autos, infrastructure, and industrial machinery.

Large Earth Magnets are essential to contemporary living. From the invention of the ferrite magnet FB1A material in 1959 to the creation of cutting-edge Neodymium magnets and the first La-Co high-performance ferrite magnet, we have continued to develop magnet materials for over 50 years, significantly advancing contemporary industry.

Our selection of Large Rare Earth Magnets includes both high-performance Giant Neodymium Magnets produced using heavy rare earth diffusion (the HAL method), which significantly reduces the use of heavy rare earth elements when compared to conventional production techniques, and high-performance Large Rare Earth Magnet produced without heavy rare earth elements like Dy (dysprosium) and Tb (terbium).

Neodymium magnet discs and cylinders with high strength
Disc magnets made of neodymium, sometimes referred to as “NdFeb,” “NIB,” or “Neo,” are the strongest rare-earth magnets on the market right now. Neodymium magnets, which come in disc and cylinder configurations, have magnetic characteristics that are significantly superior to those of any other permanent magnet materials. They have a strong magnetic field, are reasonably priced, and function well at room temperature. They are thus the most often utilized rare-earth magnets for commercial, industrial, and consumer applications.

Premium Grades & Sizes of Neodymium Disc Magnets
Magnet Shop provides a huge selection of authorized neodymium magnets for sale online at bulk reduced costs. From tiny disc magnets with a 0.1″ diameter up to massive cylinder magnets that can support 68 lbs. The highest grade now offered on the market is N52, while premium grades range from N35 to N52.

Neodymium disc and cylinder magnets are among the many items we offer; not all of them are displayed on our page. To let us know what you’re searching for, get in touch with us right once or email us a specific request.

The characteristics and features of neodymium disc magnets
Information about the approximate pull of neodymium magnets
The stated estimated pull information is just for use as a guide. These numbers were estimated based on the idea that the magnet would be fastened to a mild steel plate that was flat, ground, and 1/2″ thick. The draw force can be greatly decreased by coatings, corrosion, rough surfaces, and other environmental factors. Test the real pull in your actual application, if possible. According to the severity of a potential failure, it is advised that the pull for essential applications be de-rated by a factor of 2 or more.

Production Processes for Neodymium Magnets
Our neodymium discs are axially magnetized and sintered for maximum magnetic strength (the magnetism direction is along the axis of the magnet from the north to the south poles). Uncoated, nickel (Ni-Cu-Ni), and gold (Ni-Cu-Ni-Au) plated coatings are popular finishing alternatives. top

NdFeB disc magnet standard dimension tolerances
Based on the following parameters, standard diameter tolerances for rare earth magnets (SmCo & NdFeB)

+/- 0.004” on dimensions ranging from 0.040” to 1.000”.
+/- 0.008” on dimensions ranging from 1.001” to 2.000”.
+/- 0.012” on dimensions ranging from 2.001” to 3.000”.

The most common type of rare-earth magnet is a neodymium magnet (also known as NdFeB, NIB, or Neo magnet), which is a permanent magnet manufactured from an alloy of neodymium, iron, and boron to create the Nd2Fe14B tetragonal crystalline structure. Neodymium magnets, developed in 1982 by General Motors and Sumitomo Special Metals, are the strongest type of permanent magnet presently accessible. They have largely supplanted other types of magnets in a wide range of modern items that require powerful permanent magnets, such as motors in cordless tools, hard disk drives, and magnetic fasteners.
