· MgNi3C

MgNi₃C is a ternary intermetallic compound combining magnesium, nickel, and carbon, belonging to the family of metal carbides and magnesium-based composites. This material is primarily of research interest for lightweight structural applications and energy storage systems, where its combination of a low-density magnesium matrix with hard nickel carbide phases offers potential for improved stiffness-to-weight ratios compared to monolithic magnesium alloys. Industrial adoption remains limited, but the material family shows promise in aerospace and automotive contexts where reducing component mass while maintaining rigidity is critical.
