Products Description

High Performance custom size 4000 gauss D25 T3 magnet ring neodymium/neodimium/ndfeb/neodium /neodym disc tube magnet

Are you looking for a high-performance magnet that can meet your various needs? If so, you may be interested in our product: High Performance custom size 4000 gauss D25 T3 magnet ring neodymium/neodimium/ndfeb/neodium /neodym disc tube magnet. This product is a magnet ring made of neodymium, which is one of the strongest and most widely used permanent magnet materials in the world. Neodymium magnets have high magnetic energy, high coercivity, high remanence, and excellent temperature stability1. They are widely used in various fields, such as motors, generators, speakers, sensors, medical devices, magnetic therapy, jewelry, toys, etc2. Our product has the following features and advantages: High performance: Our product has a magnetic flux density of 4000 gauss, which is much higher than the average of 1000-2000 gauss for other neodymium magnets3. This means that our product can provide stronger magnetic force and longer magnetic range for your applications. Custom size: Our product has a diameter of 25 mm and a thickness of 3 mm, which is a common size for magnet rings. However, we can also customize the size according to your requirements, as long as it is within the range of 1-50 mm for diameter and 1-10 mm for thickness4. You can specify the size you want when you place your order, and we will make it for you as soon as possible. Multiple shapes: Our product is a magnet ring, which is a circular shape with a hole in the center. This shape is suitable for many applications, such as making magnetic bracelets, necklaces, earrings, etc. However, we can also provide other shapes, such as disc, tube, cylinder, sphere, etc. You can choose the shape you want from our product catalog, or you can contact us if you have any special requests. Durable and reliable: Our product is coated with nickel, which is a common and effective coating for neodymium magnets. Nickel coating can protect the magnet from corrosion, oxidation, and abrasion, and enhance its appearance and durability. Our product is also tested and certified by ISO 9001, CE, and RoHS, which means that it meets the international standards of quality, safety, and environmental protection.

Magnet Plating and Coating Options
The following is a list and description of common plating options for custom magnets.Why do magnets need to be plated?

★ Oxidization (Rust)
NdFeB magnets will oxidize(rust) if left exposed. When a plating wears down or cracks, the exposed area will oxidize. An oxidized area will not result in complete degradation of the magnet, only the oxidized area will lose its strength. However the magnet will lose some structural integrity and become more susceptible to breakage.

★ Durability
Depending on shape, permanent magnet substrate is brittle. A multilayered metal plating like nickel or zinc improves the magnets resistance to chipping and wear, particularly around corners.

★ Harsh Environments
Platings vary in their tolerance of different harsh chemicals and abrasion. Salt and humidity in regions near the ocean are
commonly overlooked when selecting a plating. Be sure to consider the magnets environment when selecting a plating.

The most common type of plating for neodymium magnets Nickel (Ni-Cu-Ni) Intended for indoor use. It has proven to be very resilient when subjected to normal wear and tear. However it will corrode oudoors in prolonged exposure to salt water, salty air,or harsh chemicals.

Magnetization Direction
A Magnetic field is an invisible flux moving from one end of the magnet to the other. Shown in Figure1. The flux consists of
moving or spinning electrically charged particles invisible to the eye. If the max working temperature meet the requirement ,permanent magnets can retain the magnetic field for very long time even forever. Magnets have potential energy which means that they have the ability to conserve energy. The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off.

Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.

Application Fields
Neodymium magnets are strong magnets,frequently used for many types of sectors, commercial, industrial & technical applications where strong permanent magnets are required. Due to their high-magnetic strength, components that previously had to be large and heavy can now be miniaturized by using Neodymium magnet material.Common Applications: holding systems requiring very high holding forces, sensors, reed switches, hard disc drives, audio equipment, acoustic pick-ups, headphones & loudspeakers, MRI scanners, magnetically coupled pumps · motors & generators, magnetic tool holders, magnetic bearings, door catches, dental instruments, medical devices, magnetic separators, lifting machinery, crafts & model making, hanging artwork, levitation devices, POP displays, commercial signage, packaging closures, jewelry clasps & more.

U-Polemag can make large inventory of Neodymium magnets in disc, block, rod , ring , arc & customized irregular shapes, in a wide range of shapes, sizes and grades. Just let us know what you are looking for by sending us a request for quote or contact us to discuss your specialty project.
