Abstract

A metal liner for a shaped charge device having a ductile metal matrix and a discrete second phase is provided. The allow composition is selected so the second phase is molten when the liner is accelerated following detonation. The molten phase reduces the tensile strength of the matrix so that the liner slug is pulverized on striking a well casing. The slug does not penetrate the hole perforated in the well casing by the liner jet and oil flow into the well bore is not impeded. The liner is formed by directly casting the desired alloy to the desired shape.
