Utilization of spheroidized tungsten in shaped charge systems
A shaped charge includes a casing, a liner disposed within an opening of the casing and an explosive disposed between the casing and the liner. The liner is made of a metal powder blend that includes a spheroidized metal powder. The spheroidized metal powder includes a spheroidized tungsten powder. The metal powder blend may further include a binder and a lubricant. The binder includes copper or lead. The lubricant includes graphite.
1. A shaped charge, comprising:
a casing comprising spheroidized metal powder;
a liner disposed within an opening of the casing; and
an explosive disposed between the casing and the liner,
wherein the liner is formed by pressing graphite and a metal powder blend that comprises a spheroidized metal powder into a conical shape.
2. The shaped charge of claim 1 , wherein the spheroidized metal powder comprises a spheroidized tungsten powder.
3. The shaped charge of claim 2 , wherein the metal powder blend further comprises one selected from the group consisting of copper, lead, zinc, tin, aluminum, nickel, antimony, cobalt, zinc alloys, tin alloys, aluminum alloys, and a combination thereof.
4. The shaped charge of claim 2 , wherein the metal powder blend further comprises normal tungsten powder.
5. The shaped charge of claim 2 , wherein the metal powder blend comprises greater than about 80 wt % of tungsten.
6. A method for manufacturing a shaped charge, comprising:
obtaining a spheroidized metal powder; and
preparing a shaped charge comprising:
a casing comprising spheroidized metal powder;
a liner disposed within an opening of the casing; and
an explosive disposed between the casing and the liner,
wherein the liner is formed by pressing graphite and a metal powder blend that comprises a spheroidized metal powder into a conical shape.
7. The method of claim 6 , wherein the spheroidized metal powder comprises a spheroidized tungsten powder.
8. The method of claim 7 , wherein the metal powder blend further comprises one selected from the group consisting of copper, lead, zinc, tin, aluminum, nickel, antimony, cobalt, zinc alloys, tin alloys, aluminum alloys, graphite, and a combination thereof.
9. The method of claim 7 , wherein the metal powder blend further comprises normal tungsten powder.
