Silicon Carbide Body Armor
- [Introduction]:The ballistic performance offered by the silicon carbide ceramic materials is much better than that of alumina, which makes SiC body armor ideal for use in situations where lightweight and highly effective protection are needed. This material can cover large surfaces without adding extra mass or bulk. The silicon carbide body armor can withstand the impact of NIJ Level III and higher rounds while significantly reducing or eliminating secondary injury sustained by the human body from the ballistic strike.
Apart from protecting the individuals, this material can be designed to be incorporated into protective structures that can be used to protect military equipment like vehicles and planes. Based on the desired level of protection, silicon carbide body armor can be manufactured in different thicknesses and shapes, including square and hexagonal shapes.

- Advantages
- The silicon carbide body armor we produce features a high density, reaching 3.13–3.15 g/cm³.
- Its hardness ranges from 2479 to 3099 HV, providing excellent instantaneous impact resistance.
- The flexural strength can reach 396.22–512.35 MPa, ensuring strong structural reliability under stress.
- We are equipped with five 3000-ton forming presses, enabling fast production cycles and a monthly supply capacity exceeding 10,000 pieces.
- The material offers outstanding multi-hit performance, maintaining protective integrity even under repeated ballistic impacts.
- Product Application
Due to its unique characteristics like hardness, low density, and superior ballistics, silicon carbide body armor is commonly used in military and security protection systems. The material is used in many different systems, ranging from vehicles that require bulletproof protection to ships and safes and cash-in-transit vehicles used in high-security civilian applications.
- 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.
