Abstract
A liner for a shaped charge formed from a mixture of powdered tungsten and powdered metal binder. The liner is formed by compression of the mixture into a substantially conically shaped solid body. In a preferred embodiment of the invention, the mixture comprises approximately 80 percent by weight of tungsten and 20 percent of the powdered metal binder. In a specific embodiment of the invention, graphite powder is intermixed with the powdered metal binder and tungsten to act as a lubricant. The powdered metal binder preferably comprises a malleable, ductile metal such as lead, bismuth, tin, zinc, silver, antimony, cobalt, nickel or uranium.
Claims16
A liner for a shaped charge comprising:
- a mixture of powdered tungsten and powdered metal binder including approximately 80 percent by weight of said tungsten and approximately 20 percent by weight of said binder, said binder comprising a malleable, ductile metal selected from the group consisting of lead, bismuth, silver, gold, tin, uranium, antimony, zinc, cobalt and nickel, said mixture compressively formed into a substantially conically shaped rigid body.
A liner for a shaped charge comprising:
- a mixture of powdered tungsten, powdered metal binder and powdered copper, wherein said powdered copper comprises a fraction by weight of said mixture within a range of approximately zero to twenty percent, said powdered metal binder comprises a fraction by weight of said mixture of approximately twenty percent and said binder includes a malleable ductile metal selected from the group consisting of lead, bismuth, silver, gold, tin, uranium, antimony, zinc, cobalt and nickel, and said tungsten comprises a fraction by weight of said mixture within a range of approximately eighty to sixty percent, said copper substituting said tungsten weight for weight within said ranges for said copper and said tungsten, said mixture compressively formed into a substantially conically shaped rigid body.
A shaped charge comprising:
- a housing;
- a quantity of high explosive inserted into said housing;
- and
- a liner inserted into said housing so that said high explosive is positioned between said liner and said housing, said liner compressively formed from a mixture of powdered tungsten and powdered metal binder, said mixture comprising approximately 80 percent by weight of said tungsten and approximately 20 percent by weight of said binder, said binder comprising a malleable, ductile metal selected from the group consisting of lead, bismuth, silver, gold, tin, uranium, antimony, zinc, cobalt and nickel.
