Medium- and high-density articles are formed from 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 som
Medium- and high-density articles are formed from 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.

I claim: 1. A shotgun shell, comprising: a casing containing at least wadding, a charge and a primer; a plurality of shell shot within the casing, wherein the shell shot have a density of at least 10.5 g/cc and are at least substantially formed from an alloy comprising: tungsten, wherein tungsten f
I claim: 1. A shotgun shell, comprising: a casing containing at least wadding, a charge and a primer; a plurality of shell shot within the casing, wherein the shell shot have a density of at least 10.5 g/cc and are at least substantially formed from an alloy comprising: tungsten, wherein tungsten forms a majority component of the alloy; nickel; and iron, wherein the alloy includes at least 5 wt % nickel and at least 10 wt % iron. 2. The shell of claim 1, wherein the alloy further includes at least one additional metallic component. 3. The shell of claim 1, wherein the alloy is formed from at least tungsten and iron powders. 4. The shell of claim 1, wherein the alloy includes at least 70 wt % tungsten. 5. The shell of claim 1, wherein the alloy includes 9.2-14.2 wt % nickel. 6. The shell of claim 1, wherein the alloy is softer than gun barrel steel. 7. The shell of claim 1, wherein the alloy has a nickel:iron ratio that is <1.0. 8. The shell of claim 7, wherein the alloy further includes at least one additional metallic component. 9. The shell of claim 7, wherein the alloy is formed from at least tungsten and iron powders. 10. The shell of claim 7, wherein the alloy includes at least 70 wt % tungsten. 11. The shell of claim 7, wherein the alloy includes 9.2-14.2 wt % nickel. 12. The shell of claim 7, wherein the alloy is softer than gun barrel steel. 13. A shot shell comprising a plurality of the shot formed by forming an at least generally spherical shot consisting essentially of an alloy having a density of at least 10.5 g/cc by melting at least nickel, iron powder, and tungsten powder, wherein tungsten forms a majority component of the alloy, and further wherein the alloy includes at least 5 wt % nickel and at least 10 wt % iron. 14. The shell of claim 13, wherein the alloy has a nickel:iron ratio that is <1.0. 15. The shell of claim 1, wherein the alloy includes at least 10 wt % nickel and further, wherein the alloy has a nickel:iron ratio that is ≧1.0. 16. The shell of claim 15, wherein the alloy includes 10.0-14.2 wt % nickel. 17. The shell of claim 15, wherein the alloy is softer than gun barrel steel. 18. The shell of claim 1, wherein the alloy includes manganese. 19. The shell of claim 1, wherein the alloy includes steel. 20. The shell of claim 13, wherein the alloy includes manganese. 21. The shell of claim 13, wherein the alloy includes steel. 22. The shell of claim 15, wherein the alloy includes manganese. 23. The shell of claim 15, wherein the alloy includes steel.
