Wakandan Vibranium is the “classic” Marvel Vibranium that absorbs kinetic energy:

Wakandan Vibranium absorbs vibratory or kinetic energy in its vicinity within itself. The apparent observable vibratory rate of the molecules of the Vibranium itself does not noticeably increase when the Vibranium absorbs mechanical energy. The outside vibratory energy is stored within the bonds between the molecules making up the Vibranium. As a result, a chunk of Vibranium which had absorbed a considerable amount of vibratory energy would be exceedingly hard to demolish. If enough force were applied to this chunk to smash it, the Vibranium would explode, releasing much of the absorbed energy. There are limits to the capacity of Vibranium to absorb vibratory energy, although the exact extent of these limits has not been determined.

Antarctic Vibranium is described as an “anti-metal” which has the opposite property, causing vibrations which weaken the atomic and molecular bonds of other metals.

Antarctic Vibranium has thus far been found in nature only in the isolated region of Antarctica known as the Savage Land. It is also known as Anti-Metal due to its opposite effects to Wakandan Vibranium. Antarctic Vibranium, through a means that is not understood, emanates vibrations which cause the atomic and molecular bonds in nearby metals of other kinds to weaken, which results in the liquefaction of nearby solid metals
