Δ Round Neodymium Rare Earth Disc Magnet Description 

Neodymium arc magnets for permanent motor generator magnets Description

Neodymium arc magnets is a special shape of rare earth magnet, Neodymium segment magnets are also called neodymium arc magnets, it is made by wire cutting of the block magnets. This neodymium arc magnets has a wide range of applications, it is commonly used in applications such as generator magnets motor magnets for permanent motor, both for rotors and stators, Wind turbine. 
It can also be used for personal creative design or for the computer hard disk magnet. If you are interested in the neodymium arc magnets generator magnets motor magnets for permanent motor or other application, you can send inquiry to us, size is customized as client’s requirement. 

This neodymium arc magnet is made of top quality high temperature NdFeB magnetic material under ISO 9002 quality systems.

The material is N35M with working temperature of 100℃ . It is magnetized through the thickness with the north pole on the inner diameter. The 4 pieces of this arc magnets can form a circle with OD=1.5″, ID=1.25″ and height =0.75″.

The following is the magnetic characteristics and the physical characteristics.

① Neodymium magnet production processing

Hydrogen explosion+Jet  milling+Sintering+Hypoxia operation process

Sintered NdFeB is the most  widely used rare earth/ permanent magnet material. The metallurgy powder was process  into micro-powder through special Sintering Craft. The production process iludes formula design, cast string, hydrogen explosion,Jet  milling, mixing, molding,Vacuum furnace Sintering , grinding, polishing, surface treatment(coating), packaging . through the( HD+JM+LOP )craft ,the neodymium magnet was feature with  high coercivity and high working temperature.

Round Neodymium Magnet Rare Earth Disc Magnets Packing 

We will do the magnetic shielding packaging when deliver magnet by express or by air, it will pass the DGM test. If the magnet is very powerful and total weight is heavy, we will suggest our client to deliver it by sea, it will more economical for them. For small disc magnet, we will use 8nner boxes packing in a carton. There will be a plastic gasket between each magnet if the small magnet is a little difficult to separate. If the magnet is uncoated, we will use the vacuum packing. For big magnet, there will be a Plastic gasket between big magnets, it will protect the big magnet and helpful for client to separate the magnets. ↓
