China Neodymium And Ferrite Magnets Manufacturer & Supplier 
1mm, 2mm thick permanent magnets we call it thin magnets, in fact, can be processed even thinner, less than 1mm, the benefits of thin self-evident, today mainly to introduce the permanent magnets too thin may lead to a number of problems and application considerations.
Possible effects of too thin a thickness of permanent magnets;
The first is the increased difficulty of the production process. The production process for ultra-thin magnets is more demanding and requires more precise control.
Then again, it's easy to break. Whether it is neodymium magnets or ferrite or other permanent magnet materials, they are inherently brittle and too thin magnets are prone to breakage during processing, assembly or use.
Small Rectangular Rare Earth Magnets
In terms of magnetic properties, the magnetic field strength of too-thin permanent magnets is not high, especially rare-earth magnets such as neodymium-iron-boron (NdFeB), which have high flux densities, but a reduction in thickness significantly reduces their magnetic field strength.
In addition, permanent magnets that are too thin are more likely to demagnetize.
Due to the weak magnetic force and low durability of thin magnets, they are suitable for application scenarios with low loads and small spaces. It is not recommended to use excessively thin magnets in applications requiring strong magnetism, such as high-power motors and lifting equipment, so as not to affect the performance of the equipment.
In order to cope with the possible effects of ultra-thin magnets, users need to consider the use of temperature, protective structure, and normal operation (do not against suction), etc. In the case of conditions allow, the appropriate increase in the thickness of the magnet, in order to improve its magnetic properties and structural strength.
