kinetic energy penetrators, and how are they made ?

i recently read an article on how the process of hot hydrostatic-extrustion and cold torsion will improve the performace of WHA penetrators.

but i always thought extrustion is the only way to make those tungsten bars, the article however, makes it seem that its not the mainstream way.

my question is then, how are the millions of WHA penetrators being used today made ? if not by extrustion ?

Re:

There are many extrusion methods. Wiki explains the differing methods.

[ame="http://en.wikipedia.org/wiki/Extrusion"]Extrusion - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Extruded_aluminium_section_x3.jpg" class="image"><img alt="" src="http://upload.wikimedia.org/wikipedia/commons/thumb/e/ef/Extruded_aluminium_section_x3.jpg/220px-Extruded_aluminium_section_x3.jpg"@@AMEPARAM@@commons/thumb/e/ef/Extruded_aluminium_section_x3.jpg/220px-Extruded_aluminium_section_x3.jpg[/ame]

I would guess that the article will probably discuss a specific extrusion method which would not discount the use of extrusion methods in general.

As to torsion, I had the impression that hot torsion is generally used but I can understand that cold torsion can improve uniformity in density. Torsion being twisting of the metal.

WHA, for the layman, generally refers to tungsten alloy. I would caution that Í'm not an engineer, the above should be read in that context.
