Abstract
A shaped charge liner including a composition of powders. The composition may include one or more of an aluminum metal powder and a titanium metal powder, a bronze metal powder, a tungsten metal powder and a graphite powder. Each powder of the composition may include grain size ranges that are different from one or more other powder grain size ranges. The bronze metal powder may include two or more different grain size ranges, and in some instances three or four different grain size ranges. A method of making the shaped charge liner and shaped charge with such liner having the composition of powders is also disclosed, as is a shaped charge including such shaped charge liner.
