Metal Powder Works Extends Westinghouse Contract for Nuclear Powder Development

• Contract extension with Westinghouse for next development phase
• Focus on optimizing DirectPowder™ metal powders for nuclear use
• Nuclear additive manufacturing sector growing rapidly
• Contract not financially material but strategically significant
• Collaboration supports Westinghouse’s advanced manufacturing goals

Contract Extension Signals Growing Trust in Metal Powder Works’ Technology

Metal Powder Works (ASX:MPW) has secured a three-month extension to its multi-year partnership with Westinghouse Electric Company, a titan in the global nuclear energy sector. This follow-on agreement builds on successful outcomes from earlier phases, allowing MPW to continue refining its DirectPowder™ metal powders specifically tailored for advanced nuclear applications.

Managing Director John Barnes highlighted that this extension underscores Westinghouse's confidence in MPW’s non-thermal powder production process, which reportedly outperforms traditional atomized powders. The collaboration aims to enhance powder quality and scale production capabilities, advancing the Technology Readiness Level (TRL) of components critical to Westinghouse’s next-generation nuclear manufacturing initiatives.

DirectPowder™ Process Poised to Disrupt Nuclear Additive Manufacturing

MPW’s patented DirectPowder™ process converts metal bar stock directly into high-quality powder feedstock without melting, reducing contamination risks and improving yield. The technology is particularly relevant as the nuclear sector emerges as the fastest-growing segment within energy-related additive manufacturing, driven by urgent spare parts demand and a burgeoning pipeline of small modular reactors (SMRs).

The nuclear additive manufacturing market is projected to exceed USD 40 billion in 2026, with material consumption in energy additive manufacturing expected to surpass USD 800 million by 2034. MPW’s ability to produce over 25 specialty powders, including high-strength aluminum and Zircaloy, positions it well to capture a slice of this expanding market. This development aligns with MPW’s recent scale-up achievements, including hitting 100MT annual capacity with superior yield efficiency, as noted in its NextGen powder production capacity update.

Strategic Partnership Outweighs Immediate Financial Impact

While the contract extension itself is not material from a financial perspective, the MPW board regards the ongoing relationship with Westinghouse as strategically significant. It reinforces MPW’s credibility in a highly specialised and regulated sector where trust and proven performance are paramount.

This collaboration complements MPW’s broader growth trajectory, which includes doubling powder revenue and securing defence contracts earlier this year, as well as progressing qualification of titanium powders for aerospace applications. The Westinghouse partnership thus represents a critical validation point for MPW’s technology in demanding industrial settings, supporting its ambition to embed additive manufacturing into nuclear supply chains, a sector close to mainstream adoption according to industry analysts.

Bottom Line?

MPW’s extended Westinghouse contract cements its foothold in nuclear additive manufacturing, but scaling commercial impact remains the key challenge ahead.

Questions in the middle?

• How will MPW’s powder technology perform in large-scale nuclear manufacturing environments?
• What milestones will indicate successful commercialisation beyond development phases?
• Could MPW’s partnership with Westinghouse open doors to other nuclear or energy sector clients?
