Vibranium
Vibranium is a fictional metal found in the Marvel Universe.There are two varieties of vibranium, both extremely rare and believed to be of extraterrestrial origin. Type A first appeared in Fantastic Four #53 by Stan Lee and Jack Kirby. Found in the equally fictional African nation of Wakanda, vibranium has the ability to absorb all vibrations in the vicinity.
Type B vibranium was first seen in Daredevil #13 by Stan Lee and John Romita. Type B is native to the artificially created Antarctic jungle known as the Savage Land. Type B vibranium produces, rather than absorbs, vibrations. The vibration that Type B vibranium produces liquifies all metals. Type B vibranium is found only in the Savage Land, though certain particle bombardments can convert Type A Wakandan vibranium into artificial and unstable Type B vibranium.
