A New Type of Tungsten Alloy Ball

The present invention relates to a new type of tungsten alloy ball. It is mainly applied to the high-speed impact of cluster bombs. The main features of this new type are that   the proportion of it  is great,high strength, good toughness.  It is a good high-speed impact, so that enhance the damage scope of cluster bombs. Alloy ball also joined the rare earth elements,  which prevent the tungsten grain from growing. The result is  becoming the ball and grain refinement. The rare earth elements hinder the process of diffusion of oxygen atoms in the alloy, thus  can increase the resistance to oxidation and corrosion of the alloy.
