Silicon Carbide Bulletproof Plate
- [Introduction]: The ballistic performance of silicon carbide ceramics is better than that of alumina ceramics. It is especially suitable for occasions where the amount is large and the protective armour cannot be too thick or heavy. It can effectively prevent the penetration of the bullets of firearms above level III. At the same time, it can avoid or significantly reduce mon-penetrating injuries caused by bombardment on the human body. It can be made into protective armour for weapons and equipment such as vehicles or aeroplanes, especially for armoured projectiles. And according to different protection levels, different thicknesses, shapes (square or hexagon) sizes can be customized.

- Advantages
- The silicon carbide bulletproof plates we produce have a high density, reaching 3.13-3.15 g/cm3.
- High hardness can reach 2479-3099 HV, and the instantaneous impact resistance is perfect.
- High bending strength can reach 396.22-512.35 Mpa.
- We have 5 forming presses with 3000 tons pressure, which makes the delivery time very fast. The monthly supply can reach more than 10,000 pieces.
- Product Application
Silicon carbide bulletproof plate is widely used in military protection, such as various bulletproof cars, armoured vehicles, ships, and the protection of civilian safes and cash transport vehicles, due to their high hardness, small specific gravity, large protective area, small distance between two impact points, good ballistic performance, more energy absorption after fragmentation and low price.
- Our Packing
The two packing methods we use are plywood box packing and solid wood packing, with the solid wood box requires a fumigation certificate. Depending on the various products, we will tailor the proper packaging box; Plastic foam measuring 2 cm to 3 cm thick is placed within the box and secured with row nails. To maintain the products safety during shipment, packing tape is typically used.
