Nickel/Chromium Alloy Powder (Ni80/Cr20)

Nickel Chromium Alloy Powder (Ni80/Cr20) combines the high-temperature strength, oxidation resistance, and electrical resistivity of the Ni–Cr system in a finely divided form optimized for powder metallurgy and coating processes. The 80–20 composition ensures stable performance under thermal cycling, while the powder morphology supports uniform sintering and dense coating formation. Industries such as aerospace, energy, and manufacturing use it in thermal spray coatings, additive manufacturing feedstocks, and high-temperature brazing. Specific technologies benefiting include gas turbine blade coatings, resistance heating elements formed by powder compaction, and wear-resistant overlays for industrial rollers. In research, its controlled particle size distribution and stable alloy chemistry enable reproducible studies of thermal oxidation, diffusion bonding, and electrical resistivity at elevated temperatures. Its adaptability from coating to structural applications makes it a key material for both industrial and experimental advancements.
