1.The magnetic material is the strongest type of permanent magnet in the world
2.Nd-Fe-B permanent magnet is manufactured in a wide range.

 

Attached picture show the Ring permanent magnet.

NdFeB is a type of rare-earth permanent magnet. It is madefrom an alloy of neodymium, iron, and boron to form theNd2Fe14B tetragonal crystalline structure. This materialis currently the strongest type of permanent magnet in the world.
Nd-Fe-B permanent magnet is manufactured in a wide rangeof shapes, sizes and grades according customer'sdemand.

permanent magnet ring has a very high energyproduct and coercivity, can pick up 660 times of own weight of heavy objects.
The advantage is high cost-effective, with good mechanical properties, easycutting; according customer's demand to manufacture in a wide range of shapes,sizes and grades.
The shortcoming is the low of the Curie temperature and the temperaturecharacteristics, easy to rust, oxidation, Sintered NdFeB's surface is usuallyrequired for plating such as zinc, nickel, silver, gold, etc., can also be donephosphorus treatment or spray epoxy resin to slow down the oxidationrate.
Pls see the compare of the coating's results:

For N grade Ndfeb,the Max Operating Temp is 80 degree
Nd-Fe-B permanent magnet with its excellent performance, abundant rawmaterial and reasonable price is to be rapid development and wideapplication.
Also becoming increasingly popular across a wide range of novelty productsfor markets.

The use of electro-acoustic devices work:
Speakers, hearing aids,pickups, stereo headset, electro-acoustic sensors, telephone receiver,
Smallsize, light weight, good sound quality.
Multifunction and miniaturization ofmobile phones, high-performance Ndfeb played a key role.
