· JVASP-36202· AlBN2

AlBN2 is an aluminum boron nitride composite or intermetallic compound combining aluminum with boron nitride phases, representing an emerging material system at the intersection of lightweight metals and ceramic reinforcement. This material targets applications requiring high stiffness-to-weight performance and thermal management, with potential use in aerospace structures, automotive components, and advanced thermal interface applications where conventional aluminum alloys reach performance limits. The incorporation of boron nitride phases offers enhanced wear resistance, thermal conductivity, and potential for improved high-temperature stability compared to unreinforced aluminum, though AlBN2 remains primarily in research and development stages with limited commercial deployment.
