25*2mm round magnet

ΔRound Neodymium Rare Earth Disc Magnet Description 

Disc magnet is the most popular shape of magnet which is mainly by the diameter and thickness to determine its size.

You can use small disc magnet in toy, whiteboard, wallet, education, packing box or your DIY design.

Large disc magnet generally used in industry for holding tool. 

Different people have different requirement, so the disc magnet accept client’s customized.

ΔHow to order Disc Magnet? 

Our quotation is based on your requests for magnet grade, size, coating, magnetization direction and quantity .

In order to give you our appropriate magnet for your prototype,we still need the other information from you.


Include Diameter and thickness. 

if you can provide your drawings is much better.


Could you kindly tell us the usage of magnet?

We have N35-N52 ,their have different flux and pull force.
we will recommend the right grade for you according your usage.


Does the magnet will attaching the water or exposed in the moist air?

The normal coating is Zn and Ni-Cu-Ni three players coating,
the Ni coating have better anti-corssion and anti-oxidized performance than Zn.
the black Epoxy coating we also can do ,but ask you high MOQ


Axial or Diametrical magnetizing?  

Axially magnetizing is common. 


How many pieces you will need? 

Different requirement correspond to different prices,

so we need to check this information with you clearly.


ΔDisc Magnets Production Flow (Quality Control)


jintong-production parameter-011

① Neodymium magnet production processing

Hydrogen explosion+Jet  milling+Sintering+Hypoxia operation process

Sintered NdFeB is the most  widely used rare earth/ permanent magnet material.

The metallurgy powder was process  into micro-powder through special Sintering Craft.

The production process iludes formula design, cast string, hydrogen explosion,Jet  milling,

mixing, molding,Vacuum furnace Sintering , grinding, polishing, surface treatment(coating), packaging .

through the( HD+JM+LOP )craft ,the neodymium magnet was feature with  high coercivity and high working temperature.

②Quality Level: 

Tight production process control:

1.Production process continues to improve

2.Raw material control& fine pick

3.Advanced production equipment

4.Manual picking Sample making Machine inspection

Configure high-end detection equipment

The development of proprietary cutting technology,advanced precision machine tight production process control allowed Jintong to remain at the forefront of neodymium magnet manufacturers.

1.Average force meter ( Milling particle size inspection)

2.Magnetization characteristic automatic measuring instrument  ( Issue demagnetization curve)

3.Magnetic testing equipment for measurements of Field Density and Field Strength

4.Hysteresisgraph for magnetic characteristic measurement.

ΔPacking Details:

Round Neodymium Magnet Rare Earth Disc Magnets Packing 

We will do the magnetic shielding packaging when deliver magnet by express or by air, it will pass the DGM test.
If the magnet is very powerful and total weight is heavy, we will suggest our client to deliver it by sea, it will more economical for them.

For small disc magnet, we will use 8nner boxes packing in a carton. There will be a plastic gasket between each magnet if the small magnet is a little difficult to separate.
If the magnet is uncoated, we will use the vacuum packing.

For big magnet, there will be a Plastic gasket between big magnets, it will protect the big magnet and helpful for client to separate the magnets.
