60*5*4 mm long square rare earth magnets

Δ Round Neodymium Rare Earth Disc Magnet Description 

Strong Neodymium block magnets rectangular magnets 
Permanent block magnets is a popular shape of neodymium magnets and has widely used in different fields, we also called block magnets as rectangular magnets. 
The shape and weight of block magnets is mainly decided by its length, width and thickness. 

The block magnets is often used in motors, generators, medical device, magnetic separators, Car antenna base, wind turbine or other industrial fields.

This 60*5*4 is designed to Ribbon Tweeter ,the ribbon tweeter magnet ask for such small guass tolerance to make sure the same effect both speaker sides.Also ask for strict size tolerance.

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.

①Size

Include Diameter and thickness.  

if you can provide your drawings is much better.

②Usage: 

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.

③Coating: 

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

④Magnetization: 

Axial or Diametrical magnetizing?  

Axially magnetizing is common. 

⑤Quantity:

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)  

 

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.

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.
