In short: CuCrZr (C18150) is a precipitation-hardening copper-chromium-zirconium alloy. After ageing it keeps high conductivity while offering much higher strength and hot hardness than pure copper; it is used for rocket combustion chambers, welding electrodes and induction parts.
Typical applications
- Rocket engine combustion chamber and nozzle liners
- Resistance welding electrodes
- Induction and thermal management parts
- Mould cooling inserts

Particle size and compatible processes
The standard cut is 15–53 µm, suitable for laser powder bed fusion (LPBF / SLM / DMLS) machines. Coarser cuts for DED/LMD processes can be requested. Share your machine model and layer thickness and we will confirm the right cut and batch documents together.
Frequently asked questions
Does CuCrZr need heat treatment after printing?
Yes. Ageing (precipitation) heat treatment is normally applied to increase conductivity and strength together.
CuCrZr powder price: what does it depend on?
The price depends on order quantity (kg), particle size cut, packaging (argon-filled cans or bottles), required documents (certificate of analysis, PSD report) and lead time. For a current price, state the quantity and your machine model in the quote form.
Which documents come with the order?
A certificate of analysis with chemical composition, particle size distribution (D10/D50/D90), flow and density values can be requested for each batch. Additional documents for aerospace, medical or dental projects are confirmed at the quotation stage.
