How NiCrAlTi Alloy Powder Enhances Oxidation Resistance in Aerospace Applications

Published by HUAXIAO TECH manufacturer

NiCrAlTi alloy powder is engineered for high-temperature environments that demand excellent oxidation resistance and mechanical stability. With a unique combination of nickel, chromium, aluminum, and titanium, this alloy is widely used in aerospace and energy sectors for thermal barrier coatings, turbine components, and additive manufacturing.

Optimized for High-Temperature Oxidation Resistance

NiCrAlTi is designed to form a stable, adherent oxide layer that protects against oxidation and corrosion at elevated temperatures. Its key features include:

• Strong Ni matrix with high thermal stability

• Cr and Al elements promoting the formation of protective Al₂O₃ scale

• Ti improving creep resistance and microstructural stability

These properties allow the alloy to perform reliably in temperatures exceeding 1000°C.
