AlB is an intermetallic compound in the aluminum-boron system, belonging to a family of lightweight ceramic-metal hybrids with potential for high-temperature structural applications. While primarily a research and development material rather than a widely commercialized alloy, AlB is investigated for aerospace and thermal management applications where the combination of low density with ceramic-like stiffness offers advantages over conventional aluminum alloys. Engineers consider AlB-based materials when seeking alternatives to heavier metals or ceramics in weight-critical, high-temperature environments, though processing and consistency challenges limit current industrial adoption.
