Patent attributes
A projectile includes a compacted and sintered mixture of a plurality of tungsten particles that are from about 8 microns to about 30 microns in size; a plurality of iron particles that are from about 40 microns to about 200 microns in size; and a material additive. At least a portion of the plurality of iron particles are bonded together. There are no intermetallic compounds or alloys of the tungsten particles and the iron particles formed due, in part, to the size of the tungsten particles and the size of the iron particles utilized. The final density of the projectile is from about 8.0 grams per cubic centimeter to about 12.2 grams per cubic centimeter and the final hardness of the projectile is from about 10 HB to about 50 HB. The ratio of the mixture of tungsten particles to iron particles is, by weight, from about 30:70 to about 65:35.
