Bulletproof alumina ceramic

99% alumina ceramic, with its high hardness and strength, is often used as the core protective layer of bulletproof composite materials. It mainly relies on its hardness advantage to achieve bullet breakage and kinetic energy consumption. It is mainly used in individual bulletproof inserts, bulletproof helmet liners, and composite with materials such as Kevlar fiber and ultra-high molecular weight polyethylene, with outstanding protective performance. Compared with silicon carbide and boron carbide ceramics, it has lower cost and is suitable for mass application in protective equipment for law enforcement and security personnel. In the field of civil security, it is commonly used for civil bulletproof doors and windows, bulletproof glass interlayers, auxiliary protective plates for cash transport vehicles, etc. It balances protection performance and cost, and is suitable for protection scenarios such as banks, jewelry stores, and ordinary security places. Compared with silicon carbide and boron carbide ceramics, it has a better cost-effectiveness and is easy to popularize and apply.
