Custom NdFeB Magnet Shape

As the third generation of rare earth permanent magnets, neodymium magnets are the most powerful magnets produced commercially. NdFeB arc magnets, also known as NdFeB arc magnets, are sintered neodymium magnets with unique shapes. Almost all NdFeB arc magnets are used in permanent magnet (PM) motors, generators or magnetic couplings Rotor and stator in the device.

NdFeB block magnet is available in a wide range of dimension, grade, and coatings. It is generally specified according to the Length x Width xThickness. The first two dimensions specify the pole face’s size of each magnet, then the last dimension detail the distance between the N pole and S pole, or magnetization direction. Block magnet can be further classified to rectangular magnet, slab magnet, cube magnet, and square magnet in accordance with above three dimensions. Operating temperatures of Neodymium block magnet vary among material’s grades and can be used for a huge variety of applications.

Neodymium disc magnets have become a preferred solution for a wide variety of industrial and civil applications. Neodymium disc magnet is typically measured by the diameter and thickness, then its thickness is always smaller than the diameter. The great majority of Neodymium disc magnet are axially magnetized and widely served various types of application, such as holding purpose and speaker magnet. Diametrically magnetized pattern is also available for circular magnet and most of diametrically magnetized Neodymium disc magnet are used as the sensor magnet. Production efficiency of Neodymium disc magnet has gained a remarkable development with the widely application of multi-wire sawing.

Cylinder magnet is also referred to as Neodymium rod magnet. It is similar with Neodymium disc magnet that Neodymium cylinder magnet is measured according to the diameter (D) and length (L), where the length is equal to or exceeds the diameter. The higher L/D ratio enables the axially magnetized Neodymium cylinder magnets have higher gauss value and making it well suitable for activating hall sensor and reed switch. In addition, Neodymium cylinder magnet with higher L/D ratio can also generate much stronger pull force from the relatively small magnetic pole area and exhibit superior temperature stability. Other representative application of Neodymium cylinder magnet includes magnetic bead separation rack and some holding applications.

NdFeB ring magnets are circular in shape with a concentric hole inside it. Magnet ring can be divided to pure ring or countersunk ring based on the detailed shape of the inner hole. Neodymium ring magnet should be measured by outer diameter (O.D.), inner diameter (I.D.), and thickness (T). Similar to Neodymium disc magnet, ring shaped magnet can be magnetized with its N pole and S pole opposite flat end surfaces or diametrically magnetized so as to the N pole is on one curved side and the S pole is on opposite curved side. Besides the conventional axially magnetized or diametrically magnetized magnets, radially oriented ring magnet is also available in ZHIYU. In addition, Neodymium magnets are easily corrode under humid condition and are necessary to cover with a protective coating.

In addition to the above shapes, neodymium iron boron magnets also have horseshoe, spherical, and other special shapes.Special-shaped magnets are mainly used on special occasions, such as magnetic connectors, and some non-standard components. Common heterogeneous magnets include large and small end magnets, T-shaped magnets, chamfered magnets, semicircular magnets, concave and convex magnets, and slotted magnets.The company can complete various shapes according to the drawings provided by customers to meet their needs.
