A shaped charge apparatus having an improved liner for a shaped charge constructed from a combination of powdered heavy metal and metal binder. Powdered heavy metal and metal binder is formed into a rigid shaped charge liner under very high pressure. The metal binder may be in powdered form or may be used to coat the powdered heavy metal particles prior to formation. The liner may also contain a relatively small percentage of other material to enhance lubrication or corrosion resistance.

L'invention concerne un appareil pour charge creuse équipé d'une colonne améliorée destinée à une charge creuse construite à partir d'une combinaison de métal lourd en poudre et de liant métallique. Ce métal lourd en poudre et ce liant métallique sont transformés en une colonne de charge creuse rigide à très haute pression. Le liant métallique peut se présente sous forme de poudre ou peut être utilisé afin de revêtir les particules métalliques lourdes poudreuses avant la fabrication. Cette colonne peut également contenir un pourcentage relativement faible d'autres matières afin d'améliorer la lubrification ou la résistance à la corrosion.
