Al31V19

Al31V19 is an intermetallic compound in the aluminum-vanadium system, representing a research-phase material rather than an established commercial alloy. This compound belongs to the family of lightweight intermetallics that aim to combine aluminum's low density with vanadium's high melting point and strength, potentially offering improved high-temperature performance compared to conventional aluminum alloys. While not yet widely deployed in production, such Al-V intermetallics are of academic and developmental interest for aerospace and high-temperature applications where weight savings and thermal stability are critical; however, their brittleness, difficulty in processing, and cost typically limit adoption versus mature alternatives like titanium alloys or nickel superalloys.
