Product Detail

How to choose the suitable NdFeB magnet?

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


The size can be customized,according to your requirement and here is the range of custom disc magnet sizes

Diameter(mm) Height (mm) Tolerance(mm) Direction of Magnetzation
0.5-240 H 0.5-80 +/-0.05 - +/-0.1 Axial Magnetized
0.5-60 H 0.5-40 +/-0.05 - +/-0.1 Diametrical Magnetized

If you are not sure what dimension you need, we also accept trial orders for samples of different sizes and different grades.

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. 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 operating temp. of N35M is 100 degrees Celsuis,N35 is only degrees Celsuis.

3.Magnetization direction:

Disc NdFeB magnet can be magnetized in two main ways, it depends on your application requirements.


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

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

There are other types of coatings, such as chromium (nickel chromium alloy), gold (nickel chromium alloy + gold alloy), phosphating and passivation.
