Cylindrical NdFeB strong magnets are regular shaped super magnets, we usually use D to denote the diameter and H to denote the height or thickness of the cylindrical strong magnets. For example, D5×20mm, that means the diameter is 5mm and the thickness (height) is 20 mm. The maximum super strong magnets force of the round magnet is on the largest surface of its two ends, and super magnets is axially magnetized. Of course, according to different applications, there are some customers will choose straight magnetization.
The most powerful permanent magnet offers a great return for cost & performance, has the highest field/surface strength(Br), high coercivity(Hc), can be easily formed into various shapes and sizes. Be reactive with moisture and oxygen, usually supplied by plating (Nickel, Zinc, Passivation, Epoxy coating, etc.).
Small cylinder super strong magnets can used in some magnetic health care, jewelry, electric retractable door, office white board, Ceiling lights, Mixer Magnet, electronic products, electrical magnets, handle, Decoration and so on.
Our company sells super strong magnets in various sizes, shapes and performance grades, and can customize the super magnets according to the customer's usage environment.
Powerful magnets,the third generation of rare-earth permanent magnet ,is the most powerful and advanced and advanced permanent magnet today.NdFeB is named as “Magnet King” its high remanence , high coercive force , high energy .Moreover ,powerful magnets has the high performance and high cost ration ,because of the rich rare earth resources in China and the ever-changing produciton process and technological progress.Aarth magnets can be easily foemed into various sizes and different shapes,such as segment 、ring、block andetc.The earth magnets production process is shown below.
Our company has perfect earth magnets testing instruments, for each batch of powerful magnets shipped, we will carry out strict quality control, every data of the powerful magnets is tested and recorded, so that you can use powerful magnets with peace of mind.
Aarth 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 Super Magnets And Corrosion Resistance
The material contains neodymium and iron ,so super magnets is easy to rust when exposed to air .Therefore ,it 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
