Product Introduction
Powder Introduction
CuCrNb-42 is a high-strength, highly conductive, heat-resistant copper alloy that exhibits excellent electrical and thermal conductivity as well as superior high-temperature strength. It is suitable for applications in rocket engines, such as combustion chamber liners, and demonstrates steadily growing demand and significant application potential. This material is compatible with additive manufacturing processes including SLM, HIP, DED, and hot‑press sintering.
Cr and Nb elements are uniformly distributed within the powder.
