Additive Manufacturing Metal Powders technology and investment research

Function

Gas-atomized metal powders — primarily Ti-6Al-4V, Inconel 718, AlSi10Mg, and CoCr alloys — produced with strict control of particle size distribution (typically 15-53 μm for laser powder bed fusion), sphericity, and oxygen content for use in additive manufacturing (AM) processes including laser powder bed fusion (LPBF), directed energy deposition (DED), and binder jetting. These powders enable production of complex aerospace, defense, and medical components with geometries impossible through subtractive machining: topology-optimized brackets, conformal-cooled tooling, lattice structures, and integrated cooling channels. Unlike the broader AM equipment note in Layer 4, this note focuses specifically on the metal powder feedstock — the consumable material whose quality directly determines part properties.

Why it's a bottleneck

Gas atomization is the rate-limiting process: molten alloy is poured through a nozzle and disintegrated by high-pressure argon or nitrogen jets into droplets that solidify as spherical powder particles. Achieving the target particle size distribution (15-53 μm) yields only 20-40% of the atomized material — the rest is oversize or undersize and must be remelted or sold into lower-value applications (MIM, thermal spray). Oxygen pickup during atomization is the critical quality parameter: titanium powder with >0.2% oxygen is unusable for flight-critical parts because oxygen embrittles the material. Qualification of AM powder lots for aerospace applications requires statistical sampling, chemical analysis, and test coupon builds per lot — a process that adds cost and limits supplier switching. The DoD allocated ~$3.3B to AM-related projects in FY2026 (83% increase from FY2025's $1.8B), signaling a deliberate push to scale qualified domestic powder supply.

Key companies

• ATI (ATI Inc.) — Vertically integrated from melt to gas-atomized powder for titanium and nickel alloys; one of few US-listed producers with aerospace powder qualification and DoD supply chain relevance.
• CRS (Carpenter Technology) — Major powder metallurgy capabilities for specialty alloys; record shipments and multi-year backlog in aerospace-grade materials as of Q2 FY2026.
• Sandvik (SAND, Sweden-listed) — Large global producer of gas-atomized metal powders via its Osprey brand; supplies titanium, nickel, and cobalt alloy powders with extensive aerospace qualifications (non-US listed — flagged for verification).

Open questions

• [ ] What percentage of ATI's revenue comes from gas-atomized AM powders vs. traditional melt/forge products?
• [ ] Which US-listed metal powder producers have achieved aerospace part qualification (not just powder qualification)?
• [ ] Track FY2026 NDAA restrictions on AM machine procurement from non-allied nations — how does this affect powder supplier qualification standards?
• [ ] Is the $3.3B DoD AM budget flowing to powder suppliers yet, or is it still concentrated in printer OEMs and research programs?
