Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Marcus K. Process Engineer · Aerospace OEM

★★★★★

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

Priya S. R&D Lead · Medical Devices

★★★★★

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
