About this product
A-Powder IN625 is a gas-atomized nickel-chromium-molybdenum superalloy for laser powder bed fusion (LPBF): outstanding corrosion resistance and high strength with oxidation resistance to ~980 °C, solid-solution strengthened and readily weldable. US-produced, lot-certified for production.
Why engineers choose A-Powder IN625
Four things a materials team verifies before qualifying a powder.
Outstanding corrosion resistance
Resists seawater, acids and pitting — the default superalloy for marine and chemical-processing parts.
High-temperature strength
Keeps strength and oxidation resistance to ~980 °C — exhaust, bellows and hot corrosive environments.
Lot-certified & weldable
Solid-solution strengthened — excellent as-built properties, no aging required. Full COA per lot for AS9100/NADCAP.
US-produced, fast dispatch
Made in the USA and shipped from Los Angeles in 5–10 business days. Need a tighter cut or an official purchase request? Just ask.

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.
