Tungsten Penetrator

Numerous types of penetrators exist. Tungsten is often a material of choice in the penetrator art. A typical method for fabricating penetrators from tungsten involves the use of tungsten powder metal, which is a heterogeneous mixture of tungsten and other metal powders. The mixture of powders is compacted into the desirable shape, liquid phase sintered and processed into penetrators.

Tungsten penetrator has superior, sought after properties. It may be produced by employing metal matrix composite technology. The tungsten penetrator herein differs from other penetrators in the prior art in that it is composed of tungsten whiskers. Although different crystalline orientations of tungsten whiskers may be employed within the scope of the present invention, the orientation is the one preferred.

Tungsten penetrators already in use tend to form mushroom heads upon impact of a hard target. The formation of a mushroom head decreases the penetration ability of a penetrator. Hence, the performance of a penetrator would be enhanced if the formation of a mushroom head could be eliminated.
