LEAD FREE LINER COMPOSITION FOR SHAPED CHARGES

摘要

A liner (5) for a shaped charge (1) 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 powder heavy metal is tungsten, and the preferred powder metal binder is copper. The powdered metal binder can be comprised of other malleable ductile metals such as bismuth, zinc, tin, uranium, silver, gold, cobalt, zinc alloys, tin alloys, nickel, or palladium.
