CuCrZr Powder - Same Material, Two Qualities
From SAFINA, a.s.|Published 5. 10. 2023 |3 min reading
The CuCr1Zr alloy is an alloy of copper with chromium and zirconium that achieves very high resistance with still very good electrical conductivity. It is characterized by stability even at elevated temperatures and during welding which makes it suitable for applications in aerospace and wherever components are subjected to cyclical thermal stress.
The CuCr1Zr alloy is an alloy of copper with chromium and zirconium that achieves very high resistance with still very good electrical conductivity. It is characterized by its stability even at elevated temperatures and during welding which makes it suitable for applications in aerospace or wherever the priority is placed on the lifetime of components under cyclic thermal stress.
SAFIAN has included two classes or qualities of this product for additive manufacturing in its portfolio. OBoth new products fully meet the standards for this material (C18500, CW106C). Both products have excellent particle sphericity, particle size distribution (PSD), but they differ partly in chemical composition.
Aerospace Grade | Standard Grade | |
Cu (%) | 99 | 98,9 |
Cr (%) | 0,95 | 0,91 |
Zr (%) | 0,04 | 0,067 |
Impurities (ppm) | 111 | 480 |

The standard grade powder (marked Standard Grade) is produced from the supplier’s master alloy, which undergoes a several-step input inspection to guarantee its quality for the above-mentioned standards and trouble-free use in additive manufacturing. The content of impurities (oxygen content not included) ranges up to a maximum level of 480 ppm. Standard Grade CuCr1Zr je vhodný pro většinu aplikaci a zákazníků, kteří nevyžadují nejvyšší možnou chemickou čistotu pro kritické aplikace.
The CuCr1Zr alloy for the most demanding applications with the highest chemical purity is designated as “Aerospace Grade” and is characterized by its very high chemical purity (impurity content up to a maximum level of 110 ppm). Při tohoto produktu je používána předslitina, která je vyráběna (legována) přímo ve společnosti Safina During the manufacturing of this product, a pre-alloy prepared (alloyed) directly in the Safina company, is used Thanks to this, a very high purity of the final product is achieved, which meets the requirements for use in critical applications in the aerospace industry for example.
As standard, we offer several fractions for additive manufacturing technologies such as LPBF (Laser Powder Bed Fusion), DED (Direct Energy Deposition) or CS (Cold Spray). The particle size distribution (PSD) and oxygen content can be adjusted at the customer’s request. Contact us for more information.
