Highlights

  • Metal Powder Works has received firm purchase orders for Zircaloy-4 powder from three new US customers — Oak Ridge National Laboratory, the US Army Research Laboratory, and a confidential US defence industry company — each of which is a leading nuclear or defence organisation.
  • The Oak Ridge National Laboratory order is considered material by the company due to ORNL's standing as the US Department of Energy's largest science and energy laboratory and a premier centre for nuclear materials development and qualification.
  • All three organisations are existing customers of Metal Powder Works who have previously purchased other powders from the company; these Zircaloy-4 orders represent their first purchases of this specific alloy system.
  • Delivery of all orders is expected in the first quarter of calendar year 2027, with the orders placed on standard commercial terms for evaluation and qualification purposes.

Metal Powder Works Limited (ASX:MPW) is an ASX-listed specialty materials company based in Pittsburgh, USA, that produces high-quality metal powders using its patented DirectPowder process. The company's Manufacturing technology converts bar stock into powder through a non-thermal process, enabling it to produce a range of specialty alloys including Zircaloy-4, a zirconium alloy widely used in nuclear fuel cladding and reactor components. On 5 November 2026, the company announced it had received firm purchase orders for Zircaloy-4 powder from three significant new customers in the US nuclear and defence sectors, extending its zirconium customer base into an area of strategic importance given the United States Government's renewed commitment to rebuilding its domestic nuclear industry.

The Three New Customers and What These Orders Mean

The three new Zircaloy-4 customers are Oak Ridge National Laboratory, the US Department of Energy's largest science and energy laboratory; the US Army Research Laboratory, which serves as the US Army's foundational research organisation; and a third US defence industry company whose name has not been disclosed for confidentiality reasons. Each of these organisations has previously purchased other metal powders from Metal Powder Works, but these Zircaloy-4 orders are the first for this alloy system. The company characterised the repeat custom across a new alloy as an indication of growing confidence in its DirectPowder materials.

The company considers the ORNL order to be of particular significance. ORNL is recognised as a leading centre for the development and qualification of nuclear materials, and was the laboratory responsible for placing the first three-dimensionally printed component into an operating US reactor. Supplying Zircaloy-4 powder to ORNL positions the company within the evaluation and qualification process that determines which materials are adopted in advanced US nuclear programs. The combined value of the three orders across all customers represents a near-term delivery commitment, with shipments planned for the first quarter of 2027.

Zircaloy-4, DirectPowder, and the Nuclear Materials Opportunity

Zircaloy-4 is a zirconium alloy with established applications in the nuclear energy industry, primarily as a cladding material for nuclear fuel rods and in reactor components, owing to its low neutron absorption cross-section and high corrosion resistance under reactor conditions. Zirconium powders are also used in defence applications. The United States has in recent years articulated policy goals around rebuilding its domestic nuclear industry, with next-generation reactor designs requiring specialist materials with tightly controlled chemistry and domestic Supply provenance. Metal Powder Works' managing director highlighted this policy context as a key driver behind the growing relevance of the company's DirectPowder-manufactured Zircaloy-4 in the US market.

The DirectPowder process distinguishes itself from conventional powder production methods, which typically rely on thermal atomisation. The company notes that its process achieves powder yields above 95 per cent and can convert premium bar stock into powder for a range of materials and applications. Metal Powder Works currently produces over 25 different powders including high-strength aluminium alloys, copper and copper-nickel alloys, and specialty alloys including commercially pure titanium and Zircaloy. The company was recognised as Material Company of the Year by the 3D Printing Industry Awards in 2024.

Key Takeaways

The three Zircaloy-4 orders from prominent US nuclear and defence institutions represent a qualitatively meaningful step for Metal Powder Works in its effort to establish a position within the US nuclear materials supply chain. The evaluation and qualification nature of these orders means they are early-stage engagements whose outcome — whether they lead to repeat or expanded orders — will depend on how well the DirectPowder-manufactured Zr-4 performs against the specific requirements of each organisation. The involvement of ORNL in particular, given its role in validating and qualifying new materials for advanced nuclear applications, could provide a credible reference point for further commercial development in the nuclear sector. The company and its shareholders will be watching whether these evaluation orders translate into follow-on Demand as the broader US nuclear materials supply chain continues to develop.
