Advantages of Sintered Neodymium Magnet:
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.
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.
As usual, we call them magnetic blocks, rectangular neodymium magnets, magnet blocks or neodymium bar magnets, their basic geometric shape is a rectangle. Magnetic blocks are always used in industry or labs, sometime the small magnetic blocks may be used as craft magnets for many hours of enjoyment.
