Square n52 magnets are a particularly practical and cost-effective form of extra strong magnets. Most square strong small magnets have N-S poles distributed on two larger faces. If you need to determine the very strong magnets poles, you can use our pole detector application program to determine this.
Square strong small magnetss are excellent holding magnets for magnetic boards, metal strips, or other objects with ferromagnetic surfaces such as refrigerators. You can easily attach postcards, sticky notes, photos, and other objects, to the top of a chalkboard or refrigerator. And the disc magnets can be easily removed from the adsorption surface.
Therefore, square strong small magnets are widely used in different fields.
Our company sells extra strong magnets in various sizes, shapes and performance grades, and can customize the N52 magnets according to the customer's usage environment.
Our company has perfect extra strong magnets testing instruments, for each batch of very strong magnets shipped, we will carry out strict quality control, every data of the extra strong magnets is tested and recorded, so that you can use it with peace of mind.
For the different environments and roles of N52 magnets, N52 magnets has different forms of magnetization to meet the requirements of product use.
Very strong magnets are used in different environments and have different requirements for surface plating. According to the customer's use environment, we can provide you with suitable surface treatment.
The Coating Of Sintered very strong magnets And Corrosion Resistance
The material contains neodymium and iron ,so it is easy to rust when exposed to air .Therefore ,extra strong magnets is necessary to treat the surface of neodymium ,iron and boron.
Pickling:In order to remove oxygen
Electroplating：Ni、Zn、Glod、Black Epoxy
Salt spray test（95%）：48 hours ，coating quality
