Products Description

China Wholesale Rare Earth NdFeB N52 Disc Neodymium Countersunk Magnet

Sintered Neodymium Iron Boron Magnets or "NdFeB" magnets offer the highest energy product of any material today and are available in a wide range of shapes, sizes and grades. NdFeB magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
 
Magnetic properties will differ depending upon alignment direction during compaction and upon size and shape.

Magnet Plating and Coating Options
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.

FAQ

Q: May we get a sample of the product? How to ship and how to pay ?

A: Yes,the samples testing should be necessary for first time , we would like cooperate for samples. If it's regular magnets and we have stock , we would like supply free samples for customers, if need new production , we will quote samples fee and we can accept T/T, Paypal , Western Union , Alibaba trade assurance for payment.We will send the sample to you by DHL express.

Q: What magnet materials are available?

A: There are many different magnet materials available, which we are able to provide. These include neodymium, samarium cobalt,alnico, ferrite, bonded neodymium, bonded samarium cobalt, bonded ferrite, injection molded neodymium, injection molded samarium cobalt, rubber stripping, and FeCrCu. If there is another material you wish to procure, please contact us.

Q:Can you supply custom magnets?

A: Yes, we have the capability to produce magnets to your specification in NdFeB, SmCo, AlNiCo, Ferrite, and rubberized magnet materials. You can contact us for more details .

Q:Do you have a minimum purchase order?

A: The manufacturing of magnets is a complex process, please check our production flow for more information. As considering the production time and cost, we suggest the batch order value should be more than US$3000 per time; Of course, if less than US$3000,we also would like quote our offer for your kind consideration, so we have no strict MOQ .

Q: How many days does it take to ship my order?

A: In generally, the sintering NdFeB and SmCo magnet production time is 15-25days, cast AlNiCo will take 25-30days , the magnetic assemblies will be about 30-40 days for your reference , the exact time need to be checked before the order .

Q:What elements affect the magnet price ?

A: 1. Shape and size : cylinder (DxH), cuboids(LxWxH) ,cubes, ring(ODxIDxH) belong to regular shape , arc magnets are popular used in motors or generators , before quotation and batch production , we have to confirm the technical drawing and samples, other irregular shape magnets are also can be made according to request.
