| 摘要 | 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. | ||||||
