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.

Application Fields

Neodymium magnets are known for their exceptionally high magnetic properties and are widely used in various industries due to their strength, durability, and versatility. Here are some of the application areas where neodymium magnets are commonly used:

Electronics industry - neodymium magnets can be found in almost all electronic devices including headphones, microphones,speakers, sensors, hard drives, and computer printers. These magnets help amplify sound and store data.

Automotive industry - neodymium magnets are used in various motor and machinery components including starters, alternators, and electric power steering systems. They provide a high level of power in a small, lightweight package.

Medical equipment - neodymium magnets can be found in devices such as MRI machines, which use the magnets to create a magnetic field to create detailed images inside the body.

Industrial applications - neodymium magnets are used in various industrial applications such as conveyor systems, lifting
equipment, and metal detectors.

Renewable energy - neodymium magnets play an essential role in wind turbines and other renewable energy generators, where they convert mechanical energy into electrical energy.

Household appliances - neodymium magnets are also used in various household appliances, including refrigerators, vacuum cleaners, and washing machines.

Aerospace industry - neodymium magnets are used in satellites, airplanes, and other aerospace vehicles due to their strength and light weight.

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.
