Key Takeaways
- ADDMAN will buy $8.1 – $10.8 million of Nickel‑based Alloy 718 powder from 6K Additive over a 30‑month term.
- The contract includes a structured revert‑buy‑back program, feeding unused powder back to 6K for recycling under its circular‑supply model.
- The agreement underpins ADDMAN’s expansion in aerospace, defense, and energy sectors, where Nickel 718 is the alloy of choice for high‑temperature, high‑strength components.
- The deal signals a maturing U.S. metal‑additive‑manufacturing (AM) market where material‑supply contracts are becoming as strategic as service‑provider relationships.
Introduction: A Milestone for U.S. Metal AM
After several years of incremental growth, the United States metal‑additive‑manufacturing ecosystem is beginning to exhibit the hallmarks of a scaled‑up market. While isolated pockets—such as the aerospace silencer market—already demonstrate robust demand, broader adoption still lags behind Europe and Asia. The latest 30‑month supply agreement between 6K Additive and ADDMAN provides concrete evidence that both material‑supplier and OEM sides are aligning for long‑term growth.
The Deal in Detail

Why Nickel 718?
- Yield Strength: 1,200 MPa (typical)
- Tensile Strength: 1,300 MPa
- Operating Temperature: Up to 700 °C
- Corrosion Resistance: Excellent in oxidizing environments
These properties make Alloy 718 the go‑to material for turbine blades, rocket engine components, and high‑performance fuel‑system parts—exactly the segments where ADDMAN is expanding.
Market Implications
1. Material‑Supply Contracts Gain Visibility
Historically, AM contracts have focused on printing services rather than raw‑material procurement. The ADDMAN‑6K agreement highlights a shift: OEMs are now securing long‑term powder sources to guarantee part consistency, reduce lead‑times, and lock in pricing.
2. Circular Supply Strategies Become Mainstream
The “structured revert‑buy‑back program” aligns with 6K’s circular‑supply model, which recycles unused powder back into the production loop. This reduces waste, lowers carbon footprint, and stabilizes powder quality—a critical factor for aerospace certification.
3. Strategic Drivers Quantified
By attaching a $8‑$11 M spend to aerospace, defense, and energy, the deal offers a rare, quantifiable metric of how these sectors are fueling metal‑AM demand in the United States.
Comparison: Nickel 718 vs. Alternative High‑Temp Alloys
| Property | Alloy 718 | Ti‑6Al‑4V | Inconel 625 |
|---|---|---|---|
| Yield Strength (MPa) | 1,200 | 880 | 450 |
| Maximum Service Temp (°C) | 700 | 600 | 650 |
| Density (g/cm³) | 8.19 | 4.43 | 8.44 |
| Typical AM Cost ($/kg) | 180‑220 | 150‑180 | 200‑250 |
| Key Applications | Turbines, rocket engines | Aerospace structural | Chemical processing, marine |

Outlook for U.S. Metal AM
The agreement underscores three broader trends:
- OEMs are taking a proactive role in securing material supply, reducing reliance on spot‑market pricing.
- Circular‑economy initiatives are moving from pilot projects to contractual clauses.
- High‑value sectors (aerospace, defense, energy) are translating strategic priorities into measurable spend on AM‑grade powders.
These dynamics suggest that the U.S. metal‑AM market will transition from “early‑adopter” to “scale‑up” within the next 3‑5 years, provided that supply‑chain stability and regulatory pathways keep pace.
Bottom Line
The 30‑month, up‑to‑$10.8 M Nickel 718 powder agreement between 6K Additive and ADDMAN is more than a commercial transaction; it is a benchmark of market maturity. By locking in a high‑performance alloy, embedding a revert‑buy‑back recycling loop, and explicitly linking spend to aerospace, defense, and energy, the deal illustrates how material‑supply contracts are becoming a cornerstone of the U.S. metal‑additive‑manufacturing ecosystem. Stakeholders—OEMs, service bureaus, and material producers—should watch this model closely as a template for future strategic partnerships.
