REG Metals supplies GRCop-42 Copper Alloy Spherical Powder for additive manufacturing, aerospace propulsion, rocket engine components, thermal management systems, defense, and advanced engineering applications. Originally developed by NASA, GRCop-42 is a dispersion-strengthened copper-chromium-niobium (Cu-Cr-Nb) alloy designed to combine high thermal conductivity, excellent high-temperature strength, superior creep resistance, and outstanding fatigue performance. It has become a preferred material for metal additive manufacturing of rocket engine combustion chambers and other high heat-flux components.
Manufactured using advanced Vacuum Inert Gas Atomization (VIGA) or gas atomization processes, GRCop-42 spherical powder offers excellent flowability, high packing density, low oxygen content, and consistent particle morphology, making it ideal for Laser Powder Bed Fusion (LPBF), Selective Laser Melting (SLM), Direct Energy Deposition (DED), Electron Beam Melting (EBM), and Binder Jetting applications.
REG Metals supplies high-quality GRCop-42 Copper Alloy Spherical Powder with controlled particle size distribution, spherical morphology, and low impurity levels. Custom particle size ranges, packaging options, and production quantities are available with Certificate of Analysis (COA) and complete lot traceability.
