Staballoy

Staballoy is the name of two different classes of metal alloys, one class typically used for munitions and a different class developed for drilling rods.

In a military context, staballoys are metal alloys of a high proportion of depleted uranium with other metals, usually titanium or molybdenum, designed for use in kinetic energy penetrator armor-piercing munitions. One formulation has a composition of 99.25% of depleted uranium and 0.75% of titanium. Other variants can have 3.5% of titanium. They are about 70% more dense than lead.
