<p>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.</p> |
