Neodymium magnets are most powerful of any kind of magnetic materials
Br of neodymium magnets are much more than 11,000 Gauss. Therefore, Neodymium magnets have strong holding strength on metal surface and could be used as component for holding, separating, etc. Neodymium magnets must be carefully handled to avoid personal injury and material damage due to its extremely magnetic strength and brittle property. disc ndfeb permanent magnets

Grades of Neodymium magnets:
► N35-N52
► 33M-48M
► 30H-45H
► 30SH-42SH
► 30UH-35UH
► 28EH-35EH

Neodymium Magnets
– Most powerful
– Strong resistance to demagnetization
– Low working temperature
– High cost
– Easily corrupted
– Hard and brittle
– We also provide Titanium Nitride covered Neodymium magnets upon customers’ request. (This magnet has not been tested or certified by any regulatory agency for implantation or use inside the human body. Use of this magnet is strictly at your own risk.)

Magnet Materials Neodymium Magnets Disk ,
Neodymium magnets are dark gray alloy. They are composed of neodymium, iron and boron. Density of Neodymium magnets is .27Lb/in3 (7.5g/cm3).
Neodymium magnets are manufactured in a metallurgy process through alloying, crushing, powdering, pressing w/magnetic orientation, sintering, then cutting, coating, inspecting and packing before shipment.

Neodymium magnets offer the highest (BH)max and high Hci
(BH)max, the maximum energy product, of neodymium magnets is highest of any kind of permanent magnets today in the world. (BH)max at different grades of neodymium magnets is 27 to 52 MGOe.
