What metal is bulletproof?
There’s nothing special about titanium. Don’t let those guys fool you. It depends on the strength and thickness of the material, and the power of the weapon that fired the bullet. A .22 long rifle won’t go all the way through a 6×6 wooden timber, but a .357 magnum will put a bullet through an engine block. A Kalashnikov (AK-47) will put a bullet through titanium 1/4 inch thick. But a bale of hay will stop the bullet. So nothing is magically bulletproof. It depends on a number of factors.
