· JVASP-41229· Mn2AlCr

Mn₂AlCr is an intermetallic compound combining manganese, aluminum, and chromium, belonging to the family of lightweight refractory intermetallics. This material is primarily of research and development interest, explored for high-temperature structural applications where the combination of low density with potential strength retention at elevated temperatures could offer advantages over conventional superalloys or refractory metals. Its use remains largely experimental, with development focused on aerospace, automotive, and energy sectors seeking to reduce component weight while maintaining performance in demanding thermal environments.
