It's a shield; a concave disk 2.5 feet in diameter, weighing 12 pounds. It is made of a unique Vibranium-steel alloy that has never been duplicated. During his experiments, he combined Vibranium with a steel alloy he was working with and created the disc-shaped shield. The shield has great aerodynamic properties: it is able to slice through the air with minimal wind resistance and deflection of path. Its great overall resilience, combined with its natural concentric stiffness, enables it to rebound from objects with minimal loss of angular momentum. It is, pretty much, virtually indestructible: it is resistant to penetration, temperature extremes, and the entire electromagnetic spectrum of radiation. The only way it can be damaged in any way is by tampering with its molecular bonding. The
