metal

· Zr3Al

Zr3Al is an intermetallic compound combining zirconium and aluminum, belonging to the family of lightweight refractory intermetallics. This material is of primary research interest for high-temperature structural applications where weight reduction and thermal stability are critical, though it remains largely experimental rather than widely commercialized in production engineering.
