· JVASP-16361· AlCrNi2

AlCrNi2 is an intermetallic compound combining aluminum, chromium, and nickel, belonging to the family of lightweight high-strength alloys. This material is primarily explored in research and advanced aerospace applications where thermal stability and corrosion resistance are critical, particularly in high-temperature environments where conventional aluminum alloys become inadequate. Its combination of low density with ceramic-like stiffness makes it a candidate for engine components and structural applications where weight reduction is essential without sacrificing mechanical performance.
