Alumina Armor Plate

Alumina Armor Plate is a hard ballistic insert plate made of high-purity aluminum oxide (Al₂O₃) ceramic as the impact-resistant surface, and is composed of a composite UHMWPE or aramid backing. During the fragmentation process, the aluminum oxide ceramic can absorb the energy of the bullet and prevent the splintering of the bullet after impact, thereby protecting the human body from injury. Currently, the common types of Alumina Armor Plate available on the market are: single curve/multi-curve tactical inserts: designed to fit ergonomic requirements, used for police/military carry vest; composite plates: aluminum oxide layered with other ceramics or metals to enhance multi-shot performance, anti-armor capability, and high-threat combat capability. These hard ballistic inserts are usually used in conjunction with tactical vests.

Although Alumina Armor Plate is currently the mainstream hard ballistic insert plate on the market, it has advantages such as high hardness, low density, and high ballistic strength, it also has some drawbacks: compared to silicon carbide, it is about 30% heavier at the same ballistic protection level; it has a strong fatigue sensation when worn for a long time; if internal cracks occur due to severe impact or heavy object strikes, the ballistic protection will be lost; the overall thickness of the same level of protection is higher than silicon carbide, and the wear and fit are slightly worse.
