What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

Unedited feedback from customers who reorder A-Powder IN625 Nickel Powder for Metal 3D Printing | LPBF Compatible – 10 kg / 22 lbs.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

★★★★★
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.
PS

★★★★★
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.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is IN625 Nickel Powder?
IN625 is a nickel-based superalloy powder engineered for LPBF additive manufacturing. It combines high-temperature stability, corrosion resistance, and predictable mechanical performance for critical components.
Which additive manufacturing processes are compatible?
Optimized for LPBF. Spherical particles with narrow PSD (15–53 µm) and low oxygen content (≤200 ppm) provide smooth recoating, minimal spatter, and repeatable layer deposition.
Can IN625 be heat-treated?
Yes, heat treatment enhances mechanical performance, achieving UTS 865 MPa, yield 470 MPa, and elongation 50 %.
What industries typically use IN625 powder?
Aerospace, energy, automotive, and industrial applications requiring corrosion resistance and high-temperature performance.
Why choose A-Powder IN625?
Manufactured by AO Metal with small-batch flexibility, consistent quality, fast delivery, and full traceable documentation for reliable, production-ready LPBF performance.
Is A-Powder the same quality as name-brand metal powders?
Yes. A-Powder is our own brand of industrial AM powder - gas-atomized for high sphericity and low oxygen, with a full Certificate of Analysis (chemistry, particle-size distribution, apparent density and flow rate) on every lot. You get the performance you expect from a premium feedstock, at a more accessible, published price.
Can I order a smaller quantity or a custom particle size?
Yes. We sell in small, workable volumes with no large mill minimums, and we can supply custom particle-size cuts or quantities on request - just ask us for a quote.
