1. Thermostability
Magnetic properties of NdFeB deteriorate rapidly above about 130 Centigrade, depending on the grade of material, and the permeance coefficient of the magnet in operation. The higher the permeance coefficient the magnet operates at, the higher the temperature it will withstand. High Hci NdFeB materials operating at a high permeance coefficient can operate to about 210 Centigrade. Shapes, Sizes, and Grades Available Isotropic bonded NdFeB can be specially formulated to meet special requirements, with energy products from 1 to 10MGOe, as required. ring permanent magnets

2. Largest Magnetic Force
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.

3. Surface Treatment
Neodymium Magnets are sensitive to temperature change and even lose magnet properties. They are easily corrupted in humid environment.
Surface protection is strongly recommended, such as plating, varnishing and encapsulating.

We supply any standard, custom, and OEM magnets of various shape and size from the N52, 48M, 45H, 42SH, 35UH and 33EH series at the lowest price within 10-15 days.
