Craftsmanship: It employs selective laser melting (SLM) for monolithic fabrication, using vacuum‑atomized spherical Cu–Cr–Nb powder as the feedstock. Following forming, a vacuum aging heat treatment is performed, and an integrated, built‑in regenerative cooling microchannel system is incorporated. Nanoscale strengthening phases are uniformly dispersed throughout, eliminating the need for separate components to be welded or assembled.
Application areas
The thrust chamber for a liquid oxygen–methane commercial launch vehicle has been manufactured to meet the engine’s requirements for ultra‑high‑temperature gas heat exchange and high‑temperature creep resistance, and multiple full‑scale hot‑fire tests have been successfully completed.

Equipment: SLM metal 3D printing equipment
Material: CuCrZr copper alloy powder
Craftsmanship: The laser selective melting 3D printing process employs CuCrZr chromium–zirconium copper alloy powder as the feedstock. By optimizing the alloy powder composition and printing thermal‑stress parameters to suit high‑temperature operating conditions, cracking and warping during printing are effectively suppressed. A complex integrated structure is fabricated, incorporating external heat‑dissipating fins and internal cooling channels; this eliminates the conventional segmented welding and assembly approach, enabling the one‑step formation of a monolithic component.
Application areas
High-temperature heat-exchange components for aerospace engines and injection-cooling structures for rocket engines
