Does a matching median size prove two metal powders are equivalent?
No. Shape, distribution tails and other material attributes can differ. Choose the measurements needed for the actual process or material decision.
Select the parameter that connects to the quality question: an equivalent particle size, a geometric dimension or a shape measure. Then record the distribution basis and dispersion procedure. Density, surface and pore-related measurements address additional material properties and should not be inferred solely from size and shape data.
How can images explain a metal-powder size result?
If two lots have similar volume medians, inspect particle images for fused particles, elongated shapes and unusual coarse particles. Keep the portion and dispersion representative in both measurements. Microtrac describes metal-powder examples using CAMSIZER X2 and SYNC.
Method details to record
| Consideration | What to record |
|---|---|
| Powder context | Alloy and processing history |
| Required attributes | Size, shape or other properties |
| Comparison basis | Dispersion and reported parameters |
Which measurement is needed for a density or porosity decision?
Specify the density or pore property separately and use a method that measures it. A size-and-shape comparison can identify geometric differences while leaving the internal structure of the particles unresolved.
