The molybdenum allows a higher density liner to be formed to create denser jets for achieving deeper penetration, but without the negative effect that often accompany the use of higher density materials. The molybdenum may be used in the amount of 0.5% to 25% by weight of the metal mixture, with tungsten and other constituents forming the remainder of the mixture.Other References
