what is captain americas shield made of in the comics
Captain America's shield Captain America's shield is virtually indestructible under normal conditions.[1] While cosmic and magical or godly opponents have broken the shield, the shield proves strong enough to absorb Hulk's strength, and repel an attack from Thor's mystical hammer Mjölnir without any visible damage. Due to its construction of a vibranium and proto-adamantium alloy, it is able to absorb all kinetic energy and transfers very little energy from each impact, preventing Captain America from feeling recoil or transferred impact forces when blocking attacks. This alloy also allows him to deflect adamantium blades without damage to the shield. These physical properties also means the shield can bounce off of most smooth surfaces, ricocheting multiple times with minimal loss in aerodynamic stability or velocity. The shield can also absorb the kinetic impact of a fall, allowing Captain America to land safely even when jumping off of several stories, a demonstrated in Captain America: Winter Soldier.[volume & issue needed]
