Description of key information

The particle size distribution of two NdBFe alloys were determined by VACUUMSCHMELZE GmbH according to a scientifically accepted method.

Additional information

The typical particle size distribution depends in each case on the quality of the imported material.

NdBFe bookmold:

The particle size distribution of NdFeB alloy particles smaller than 32 micrometer is as follows:

D10: 6.5 micrometer

D50: 19.2 micrometer

D90: 38.3 micrometer

NdBFe strip cast:

The particle size distribution of NdFeB alloy particles smaller than 32 micrometer is as follows:

D10: 5.3 micrometer

D50: 14 micrometer

D90: 28.1 micrometer
