We are all familiar with rare earth neodymium iron boron, and the main reason for choosing it is its strong magnetic properties. However, its weakness lies in its susceptibility to corrosion and oxidation. Some netizens may ask, what are the effects of neodymium iron boron strong magnetic magnet oxidation, such as whether the magnetic properties will decrease?
This is mainly divided into long-term and short-term. If neodymium iron boron magnets rust in the short term, it will not have any impact on the magnetic force. Therefore, a small number of customers do not have such high requirements for magnets and do not need surface treatment.

In the long run, when the plating layer is damaged, the magnetic material itself may corrode, pulverize, or even partially detach, resulting in changes in the actual size and shape of the magnet. For products that require high dimensional accuracy, this impact needs to be particularly noted.
In summary, the oxidation of neodymium iron boron magnets will not affect their magnetism in the short term, but in the long run, there will be a decrease in magnetic force. Additionally, if neodymium iron boron magnets are exposed for use, oxidation may not result in a visually appealing appearance.
For neodymium iron boron magnets, surface protection is very important. Currently, the most common method is nickel copper nickel three-layer electroplating, also known as Ni Cu Ni coating, which can provide moisture resistance, rust prevention, and protection. In addition, surface treatment methods such as galvanizing and epoxy resin can also be selected based on the product's usage environment.
