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. |

A method of producing a liner (5) for a shaped charge (1) comprising mixing a composition mixing a composition of powdered metal with plasticizers and binders to form a paste. The paste is then particulated and injected into an injection mold. The paste is molded into a molded liner shape (5) and then chemically treated to remove plasticizers and binders from the molded liner shape. After being removed from the injection mold the molded liner shape is sintered inside of a furnace. The powdered metal composition can be comprised of a mixture of from 60 % to 97 % by weight of powdered heavy metal and from 40 % to 3 % by weight of cobalt, or the powdered metal composition can be comprised of a mixture of from 60 % to 97 % by weight of powdered heavy metal and from 40 % to 3 % of copper, the preferred heavy metal being tungsten. |

A shaped charge apparatus having an improved liner for a shaped charge constructed from a combination of powdered heavy metal and metal binder. Powdered heavy metal and metal binder is formed into a rigid shaped charge liner under very high pressure. The metal binder may be in powdered form or may be used to coat the powdered heavy metal particles prior to formation. The liner may also contain a relatively small percentage of other material to enhance lubrication or corrosion resistance. |

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. |

A liner for a shaped charge comprising powdered heavy metal tungsten coated with a metal binder coating compressively formed into a liner body. Each of the powdered heavy metal particles are substantially uniformly coated with metal binder coating. The preferred powdered heavy metal particles are comprised of tungsten. Optionally, the liner for a shaped charge includes a lubricant intermixed with the coated heavy metal particles. The metal binder coating is selected from the group consisting of copper, lead, nickel, tantalum, other malleable metals, and alloys thereof, and comprises from 40 percent to 3 percent by weight of the liner. The powdered heavy metal particles comprise from 60 percent to 97 percent by weight of the liner. |

An improved shaped charge liner for the use of minefield clearance. The liner being elongated and of substantially uniform cross-sectional thickness with an apex, a central region, and a base. It is assembled with an explosive body to form a munition such as a grenade. The explosion causing the liner to form a high velocity tip, a medium velocity middle segment, and a large trailing slug. There is an outwardly extending segment in the central region which is adapted to flow metal into the high velocity tip to provide the middle segment with at least sufficient energy to penetrate and explode munitions while the tip has sufficient energy to penetrate soil. |
