Micron D10   14.5 D50   20 D90   25.87 90% of the particles are 25.87 micron or smaller Apparent Density: about 4 g/ccNote: Pure copper powders do not show continuity or conductivity by a multimeter. I think there are two reasons for that. One is the low voltage used for the test. The other is lots of air and weak contacts between the particles. They will show conductivity with higher voltage, when they are compacted and when they are mixed with some oil or resin to form a paste.
