Neodymium magnets have the advantages of strong magnetic force and small size, but the material itself is brittle. When subjected to impact, drop, or assembly impact, it is easy to have missing corners, cracking, or even fragmentation. Is there any way to improve the impact resistance of neodymium magnets? Xiao Fu has compiled some useful methods.
Firstly, neodymium iron boron magnets can be sintered, bonded, or injection molded. While allowing for a decrease in magnetic properties, injection molded neodymium iron boron magnets (coated with magnetic powder on a plastic substrate) can be preferred as an effective way to improve impact resistance.
But more often than not, customers choose sintered neodymium iron boron magnets. How can this type of magnet improve its impact resistance?

In terms of exterior design, right angle and sharp corner positions are prone to stress concentration, such as square shaped and rectangular magnets, which can increase the inverted R angle and effectively reduce the probability of impact missing corners. Avoid being too thin when using.
In terms of surface protection, ordinary galvanizing and nickel plating cannot change the brittleness of the magnet itself. It is better to add plastic, glue, or steel sleeves or aluminum shells to provide good cushioning and withstand impact with structural components.
The above is an introduction to effectively improving the impact resistance of neodymium iron boron magnets. If your company needs customization, wholesale, or quotation for permanent magnets, please contact the website customer service.
