A liner for a shaped charge formed from a mixture of powdered heavy metal and a powdered metal binder. The liner is formed by compression of the mixture into a liner body. In one embodiment of the invention, the mixture comprises a range of 50 to 93 percent by weight of tungsten, and 50 to 7 percent by weight of the powdered metal binder. In a specific embodiment of the invention, graphite powder is intermixed with the powdered metal binder to act as a lubricant during formation of the shaped charge liner. The powdered metal binder can be a combination of copper powder, lead, and molybdenum.

Shaped charges having enhanced tungsten liners

A liner for a shaped charge formed from a mixture of powdered heavy metal and a powdered metal binder. The liner is formed by compression of the mixture into a liner body shape. In the preferred embodiment of the invention, the mixture comprises a range of 90 to 97 percent by weight of powdered heavy metal, and 10 to 3 percent by weight of the powdered metal binder. In a specific embodiment of the invention, a lubricant is intermixed with the powdered metal binder to aid in the formation of the shaped charge liner. The preferred powdered heavy metal is tungsten, and the preferred powdered metal binder is copper. The powdered metal binder can be comprised of other malleable ductile metals such as bismuth, zinc, tin, uranium, silver, gold, antimony, cobalt, zinc alloys, tin alloys, nickel, or palladium.
