Description of CuCrZr Powder (15-53 um)
CuCrZr, also known as C18150, is a high-performance copper alloy composed of copper with small amounts of chromium and zirconium. This alloy is renowned for its excellent combination of high strength, conductivity, and resistance to softening at elevated temperatures. It is widely used in industries such as aerospace, automotive, electrical, and additive manufacturing for critical components requiring both strength and conductivity.
Manufacturing method of CuCrZr Powder (Gas atomization)
- Raw Material Preparation: High-purity copper, chromium, and zirconium are used as raw materials.
- Melting and Alloying: Raw materials are melted under high vacuum or inert gas protection using arc melting
- Atomization for Powder Production: CuCrZr powder is produced using gas atomization, powder bed fusion, or plasma rotating electrode process (PREP)
- Post-Treatment: Powders undergo degassing and surface cleaning to reduce oxygen content.

CuCrZr alloy produced by laser powder bed fusion: Microstructure, nanoscale strengthening mechanisms, electrical and mechanical properties
Abstract: CuCrZr is a precipitation hardening alloy, used for its good electrical and thermal properties combined to high mechanical properties. Using additive manufacturing technologies, and more specifically the laser powder bed fusion (L-PBF) process, allows designing highly complex parts such as compact and efficient CuCrZr heat exchangers. Additional understanding of the specific CuCrZr metallurgy during this manufacturing process is still needed to fully take advantages of these possibilities. This work aimed (i) to clarify the impact of the L-PBF process and post-fabrication heat treatments on the microstructure of L-PBF CuCrZr alloy, (ii) to determine the corresponding mechanical and electrical properties and (iii) to quantify the contributions of the different nano-scale strengthening mechanisms (nano-precipitation, dislocations, solid solution, grain size refinement) depending on the different heat treatments. The microstructures of the CuCrZr samples are carefully analyzed at different scales thanks to scanning electron and transmission electron microscopy, highlighting the effect of the different heat treatments.
