· In2 Cu4

In₂Cu₄ is an intermetallic compound combining indium and copper in a fixed stoichiometric ratio, belonging to the family of binary metal intermetallics. This material is primarily of research and specialized industrial interest, investigated for applications requiring the unique combination of indium's softness and thermal properties with copper's electrical conductivity and mechanical stability. The compound is notable in electronics and materials science contexts where tailored intermetallic phases offer advantages over conventional alloys or pure metals in specific high-reliability or high-temperature environments.
