…and bulletproof, to boot.
"Dr. Vecchio’s group has been getting calls from aerospace companies and other businesses fascinated by his reports on a new, extraordinarily hard, strong and tough material whose raw ingredients are aluminum and titanium. When his team gets done with it, the stuff is stiff as steel at half the weight. It is harder than brick. If it cracks, the crack splits into ever smaller cracks that wander about and often fade away, with no shattering.
Dr. Vecchio reports in this month’s Journal of the Minerals, Metals and Materials Society that it not only makes a good lightweight structural material, it performs “spectacularly” on depth-of-penetration tests - another way to say it stops bullets. (In the lab, a tungsten rod fired at 2,000 miles per hour penetrated only halfway through a three-quarter-inch-thick sheet of Dr. Vecchio’s material.)
It also seems to possess qualities needed for lightweight armor and for aerospace applications where strength, low weight and good heat conductivity are at a premium."
