· Al1 Re2

Al₁Re₂ is an intermetallic compound combining aluminum and rhenium in a 1:2 stoichiometric ratio. This material belongs to the family of lightweight refractory intermetallics and is primarily of research and development interest rather than established commercial production. The compound is investigated for potential high-temperature applications where the low density of aluminum combined with rhenium's exceptional refractory properties could offer advantages in aerospace and extreme-environment systems, though processing challenges and cost currently limit practical deployment.
