Product features

Alumina ceramic bullet proof plate has high specific stiffness, high specific strength and chemical inertia in a variety of environments. Its advantages over metal are that metal materials will produce plastic deformation and absorb energy when resisting bullet impact, while alumina ceramics will almost not produce plastic deformation. By virtue of its high strength and hardness, the bullet will be passivated or even broken. In the process of forming small and hard fragments on the ceramic surface, they will be crushed and absorb the energy of high-speed warheads.

Application

Human body, vehicle body, armor, building shelter protection
