CuCrZr Copper Alloy Powder
Copper Alloy Powders · Metal Additive Manufacturing Powder
CuCrZr (C18150) is the leading copper alloy for AM thermal management: rocket combustion chambers, induction coils, welding electrodes and heat exchangers where both high thermal conductivity and moderate strength are required. Unlike pure copper, CuCrZr prints on laser systems with infrared lasers thanks to its chromium and zirconium additions, which cut reflectivity and enable stable melting. As-built CuCrZr reaches ~420-480 MPa UTS; ageing (450-500°C) precipitates Cr and Zr phases, lifting strength while retaining 320+ W/mK conductivity. Gas-atomized powder in 15-45 µm and 15-53 µm cuts is standard. Buyers should verify chromium 0.5-1.2% and zirconium 0.03-0.3% on the certificate and confirm the supplier's oxygen control (≤600 ppm typical).

Frequently Asked Questions
How much does CuCrZr powder cost?
CuCrZr AM powder typically quotes $60-120 per kg. Verified suppliers on this page provide current quotes, usually within 24 hours.
Can I print CuCrZr on a standard IR laser machine?
Yes — unlike pure copper, CuCrZr absorbs infrared laser energy well enough for stable LPBF printing, which is why it is preferred over pure copper for thermal parts.
What heat treatment does printed CuCrZr need?
Solution anneal (~980°C) followed by ageing at 450-500°C for 2-4 hours precipitates Cr/Zr phases, maximizing strength with conductivity above 320 W/mK.
Which particle size should I order for heat exchangers?
15-45 µm for thin walls and fine channels; 15-53 µm for larger thermal components. Specify wall thickness in your inquiry.
Why choose CuCrZr over pure copper?
CuCrZr gives up some conductivity (320 vs 390 W/mK) for much easier printing and age-hardenable strength — the practical choice for combustion chambers and coils.
