Feature: Very small granule, this powder used to make the bonded NdFeB. Have different

grades.

Our bonded powder is an RE-Fe-B alloy composition that rapidly 

solidifies from a molten state at extremely high cooling rates, 

on the order of 1,000,000 degrees per second. 



This rapid solidification results in a material that has an extremely 

fine (typically 30-50 nanometer) metallurgical grain structure. 



Therefore, the consequent grain size is smaller than the critical 

size for a single magnetic domain, and thus these materials are 

magnetically isotropic. 



Furthermore, in contrast to the fine, anisotropic powders that are 

used to manufacture sintered RE-Fe-B magnets, powder is relatively 

stable against oxidation-induced demagnetization. 



These characteristics make powders ideally suited for the production 

of bonded permanent magnets.
