Product Detail

How to choose the suitable NdFeB magnet?

If this is not your first time purchasing for magnets,then you know exactly what size,grade,coating and magnetization direction you needs.You can send us a RFQ directly by email or "leave us message",and we will respond to you within 24 hours.

If you're purchasing magnets for the first time,let's share the following informations:


The size is determined by your applications.

As a manufacturer,we produce magnets for each order according to customers' requirements.If you can provide accurate measurements and tolerances of magnet,it is very helpful for quotation and production. 

Even if you're not sure what size you need, we accept sample orders of different sizes.That way you can test them and ultimately help you develop new product/project successfully.

2.Grade of NdfeB Magnet: 

If your application is at room temperature only,the N series is the best choice,with a max operating temperature 80 degrees Celsius. In the N series,the N55 grade has strongest magnetic force,and is also the most expensive. Generally speaking,the N35 grade is relatively cost-effective and also have strong magnetic force.But which grade to choose depends on your pursuit of magnetic force or say application.

The higher the temperature of resistance of the magnet,the more expensive it is.For example,N35 grade and N35M grade have the same magnetic force,but the max opearting temp. of N35M is 100 degrees Celsuis

3.Magnetization direction:

Usually,adhesive NdFeB magnet is axial magnetized,so that the contact surface have the max magnetic force.And it's can be matched pairs,the adhesive is on the north pole of one magnet and on the south pole of the other.


Nickel and Zinc coating are the most common,the salt spray test can meet the requirement of 24-48 hours.

Eopxy coating have excellent against humidity and salt spray environments,the salt spray test can reach 48-72 hours.

And there are other types of palting,like chrome(NiCuNi+Cr),gold(NiCuNi+Au),phospahted,passivation.
