Methods for producing medium-density articles from recovered high-density
tungsten alloy (WHA) material, and especially from recovered WHA scrap. In one
embodiment of the invention, the method includes forming a medium-density alloy
from WHA material and one or more medium- to low-density metals or metal alloys.
In another embodiment, medium-density grinding media, such as formed from the above
method, is used to mill WHA scrap and one or more matrix metals into particulate
that may be pressed and, in some embodiments, sintered to form medium-density articles therefrom.
