ABSTRACT:
Medium- and high-density articles are formed from melting and casting alloys containing tungsten, iron, nickel and optionally manganese and/or steel. In some embodiments, the articles have densities in the range of 8-10.5 g/cm3, and in other embodiments, the articles have densities in the range of 10.5-15 g/cm3. In some embodiments, the articles are ferromagnetic, and in others the articles are not ferromagnetic. In some embodiments, tungsten forms the largest weight percent of the alloy, and in other embodiments the alloy contains no more than 50 wt % tungsten. In some embodiments, the articles are shell shot.
