Can neodymium iron boron magnets achieve 300mm specifications?

As a functional product, magnets generally need to be customized to meet the magnetic requirements of their own products in addition to commonly used specifications. So, what specifications can NdFeB magnet manufacturers generally make?
 
What is the maximum size of Xiamen everbeen neodymium iron boron strong magnet?
 
Recently, a project of a diving and salvage company asked: Can the diameter of your magnet be 30mm? This is completely possible.

So can the neodymium iron boron strong magnet be up to 300mm?
 
Generally speaking, it is possible for a NdFeB strong magnet to be more than 200mm. A colleague came into contact with a customer who asked for a NdFeB ring with an outer diameter of more than 220. Because the size is so large, the quantity is generally required. There won’t be too many, maybe a few or a dozen. 300mm powerful neodymium iron boron magnets cannot be made. First, there is no such big mold, and second, making such a big magnet is easier to break and it is not easy to magnetize.
 
Description of high temperature demagnetization of sintered NdFeB magnet
 
Xiamen everbeen sintered NdFeB magnets high temperature demagnetization problem is well known to us. The combination of cost and performance from sintered NdFeB magnets makes them a popular choice for the use of traditional magnets and the creation of new product applications, which are sharp in existing strength The increased case allows the use of a smaller magnet, which is advantageous for most designs.
 
The handling procedures of sintered NdFeB magnets at high temperatures need to be careful, because sintered NdFeB magnets are easily demagnetized at high temperatures. Xingchuang will work with you to understand and explore the high-temperature demagnetization of neodymium sintered iron boron magnets. Due to the high content of neodymium iron in sintered neodymium iron boron magnets, they are also easy to oxidize. Therefore, the various coatings that meet these conditions depend on the operating environment of the sintered neodymium iron boron magnets.
 
 
Xiamen everbeenU magnet
Standard configuration: Generally speaking, Xiamen everbeen sintered NdFeB magnet is divided into two main column lists: CD and block.
 
The strength of these magnets requires careful handling. Small magnets attract from a distance and large magnets can cause pain and even break when damaged.
 
The new optical disc cylinder is called "optical disc", which is generally marked by a high magnet with a diameter of a cylinder, usually the diameter of a tall cylinder.
 
The new linear block is a rectangular or square cross-section with a variety of thickness options, rare earth samarium cobalt neodymium boron (neodymium iron boron) is an alternative, as a samarium cobalt magnet can withstand higher temperatures, more corrosion resistance, and neodymium Iron and boron are comparable.
 
Samarium cobalt is more expensive than neodymium iron boron in terms of market price sensitivity. Samarium cobalt is used in computer disk drives, sensors, traveling wave tubes, linear actuators, satellite systems and some motors.
