ABSTRACT:
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.
