Powder Alloy Corporation Expands Production Capacity for GRX-810 and GRCop-42 with Advanced Melting and Atomisation Upgrades!
Powder Alloy Corporation (PAC), headquartered in Loveland, Ohio, has announced a major expansion of its manufacturing capabilities aimed at supporting the growing global demand for next-generation aerospace and high-temperature materials. Central to this initiative is the installation of a new Vacuum Induction Melting (VIM) furnace, complemented by upgrades to the company’s inert gas and vacuum melting technologies. These investments represent a significant step in strengthening PAC’s position as a critical supplier of advanced metal powders for mission-critical applications.
Alongside the new VIM furnace, PAC has added eight atomisation furnaces to its production infrastructure. This expansion substantially increases the company’s ability to scale powder output while maintaining the tight metallurgical control required for advanced alloys. With these additions, PAC can now support both large-volume production and specialised alloy runs simultaneously, enabling greater flexibility and responsiveness to customer requirements across aerospace, propulsion and extreme-environment applications.
The expanded capabilities are particularly important for meeting rising demand for two high-performance materials: GRX-810 and GRCop-42. GRX-810 is a NASA-developed oxide dispersion strengthened (ODS) alloy designed to deliver exceptional strength, oxidation resistance and durability at extremely high temperatures. GRCop-42, a copper-chromium-niobium alloy, offers high thermal conductivity combined with excellent strength, making it well suited for propulsion systems and thermal management applications. These materials are increasingly critical as aerospace and space exploration programs push performance boundaries.
According to Richard Meklus, Vice President of Additive Materials at Powder Alloy Corporation, the expansion directly supports the industry’s evolving material requirements. He stated that the addition of the new VIM furnace and the scaling of melting technologies significantly increase melt capacity, improve delivery timelines and reinforce PAC’s role as a trusted supplier for advanced aerospace and propulsion programs. The upgrades also enhance consistency and precision across the company’s powder portfolio.
PAC emphasized that the expanded atomisation and melting infrastructure provides the level of control, reliability and process stability required for next-generation alloys. By combining vacuum induction melting with advanced inert gas atomisation, the company can produce powders with tightly controlled chemistry, microstructure and particle size distribution—key factors for Additive Manufacturing and other high-performance fabrication processes.
These investments reflect PAC’s long-term commitment to serving industries that operate in extreme and unforgiving environments, where material performance and quality consistency are non-negotiable. As demand continues to grow for high-strength, high-temperature alloys in aerospace, defense and space exploration, the company believes its upgraded facility is well positioned to support future engineering breakthroughs.
The new VIM furnace has now been fully commissioned and is scheduled to begin production in January 2026. With these enhancements in place, Powder Alloy Corporation is preparing to meet increasing global demand with greater scale, speed and confidence, while maintaining the high quality standards that advanced applications require.
