Hello everybody.
Currently I'm working on Hard Ferrite Magnets. There are different grading systems, as American, Europe and Chinese. Chinese system is currently used more often. Two famous grading are Y30 and Y35. Their differences is in their magnetic properties. Does anybody knows difference in production process of these two grading? Or any other grading.
Is it because of different additives they have? Or different manufacturing method?
I would be thankful if anybody gives me information or datasheet regrading question
I am not a specialist in this, but as far as I understand, classic grading is based on tabulated properties, which are reached with proprietary composition. different manufacturers can implement different balance of components and curing regime, but on x-ray spectrogram they look more or less the same inside the same class.
