Product Introduction
Alumina Ceramic Ballistic Plates are hard bulletproof plates made by pressing together ceramic blocks of alumina and high-strength polyethylene (UHMWPE) or aramid (Kevlar) composite backing plates. Alumina is one of the most cost-effective materials in advanced ceramics, featuring high elasticity, high refractoriness, high hardness, and relatively low cost. It is currently the most widely used and cost-effective rifle-level bulletproof material in the hard bulletproof clothing market. There are mainly two types: one is a single large plate, made from a complete piece of ceramic plate; the other is a mosaic/hexagonal composite plate, made by fitting many small square or hexagonal ceramic pieces onto the backing plate.
The major advantages of Alumina Ceramic Ballistic Plates
Price advantage:
The cost is 40% to 60% lower than that of silicon carbide, suitable for large-scale mass production, training consumables, and strong vehicle armor stability: not afraid of moisture, water immersion, drastic temperature changes. The performance degrades slowly in humid coastal and rainforest environments.
Flexible processing:
Can be made into flat plates, curved human body surfaces, irregular cutting, and stable delivery.
Good impact resistance:
The ceramic matrix has sufficient rigidity and balanced performance in resisting shrapnel and explosive shock waves.
