· JVASP-51338· FePbW2

FePbW2 is an iron-lead-tungsten ternary alloy combining the mass-damping properties of lead with the strength contribution of tungsten in an iron matrix. This material family is typically pursued in research and specialized applications where high density, vibration damping, and radiation shielding are simultaneously required, though commercial adoption remains limited compared to established alternatives like lead-free brasses or tungsten-heavy alloys.
