Abstract
A liner for a explosive shaped charge, such as those used in perforating operations in oil and gas wells, is formed from a powdered metal mixture that includes molybdenum. The molybdenum allows a higher density liner to be formed to create denser jets for achieving deeper penetration, but without the negative effects 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.
