What is Silicon Carbide Armor
Silicon carbide armor is made from advanced ceramic SiC, known for its high hardness, low weight, and impact resistance. It is widely used in body armor, vehicle and aircraft protection, and ballistic shields. Silicon carbide armor offers reliable defense against bullets and shrapnel while remaining lightweight, ideal for military, law enforcement, and aerospace use. Balancing performance, cost, and weight, it is often commonly used over alumina and more expensive boron carbide.

The strongest body armor in the world combines ceramic strike faces with advanced backing materials. Among these, silicon carbide (SiC) and boron carbide (B4C) ceramics are the most advanced.
Newthink silicon carbide armor plates are ≥26 GPa in hardness and ≥2700 MPa compressive strength, stopping high-velocity rifle rounds and still light. Compared with alumina in traditional armor, our silicon carbide armor is 30% lighter with better multi-hit capability and is among the best available in the world.
Silicon carbide armor is used in:
Body armor (torso, side, shoulder plates)
Vehicle and aircraft armor (lightweight ballistic panels)
Tactical shields and riot barriers
Anti-drone and UAV protection
Its multi-hit capability, lightweight, and corrosion resistance make it ideal for military, police, and high-risk industrial protection.
Ceramic plates provide hard, high-hardness surfaces which have the ability to defeat armor-piercing ammunition.
SiC ceramic plates can be used to arrest 7.62mm NATO steel-core bullets while keeping the plate weight low—typically 2.5–3.6 kg per torso plate. Their fracture behavior dissipates impact energy and prevents over-penetration, which is crucial in combat and police use.
The production of ceramic armor involves the following steps:
Powder Selection – Using high-purity silicon carbide powder
Forming – Shaping through dry pressing, slip casting, or CNC molding
Sintering – Densifying the material at temperatures exceeding 1650°C
Machining – Conducting precision CNC cutting and surface grinding
Inspection – Performing dimensional, ballistic, and structural quality checks
Silicon carbide sits between alumina and boron carbide on the trade-off spectrum of weight, performance and cost.
Alumina is the most economical one with mature technology. But among the armor materials, it is the heaviest. It is used for basic vehicles and low-cost panels.
Boron carbide is the lightest and hardest one. It gives the best protection per kilogram. However, B4C is extremely expensive and brittle. It’s only reserved for the highest-end and weight-sensitive applications.
SiC offers a comprehensive performance of lightweight, hardness and stiffness. It has a far more attractive price point than B4C, resulting in widespread use in modern defense plate systems.
In practice, you can choose alumina for lowest cost, SiC for the best cost-effectiveness, and B4C when you must achieve the best results for high-end applications. Remember that ceramic plates are only one part of ballistic systems. Backing materials and design are also important.
Silicon carbide provides good strength and weight. In virtue of the Mohs hardness of 9.5, it will readily dull projectiles, while acting as an effective energy-dissipater. Additionally, it’s remarkable low density ~3.2 g/cm3 (lighter than steel and alumina) provides less load while delivering high impact resistance. The high stiffness minimizes additional weight but effectively holds the energize it will dissapear with withstand and moderate. For this reasons, SiC has become a highly economically and practically superior option in the development of modern lightweight armoring systems.
Silicon carbide armor achieves stronger ballistic protection with less weight. The chief advantage is its low density, approximately 40% lower than that of steel. Thus, SiC plates can yield equivalent to or better protection at half the weight, leading to increased mobility and endurance.
Steel absorbs energy by plastic deformation. Unlike it, SiC armor defeats bullets through “consume and crush”. Upon impact by a projectile, SiC armor either blunt or shatters the bullet tip instantaneously. During the time the tip is fracturing, the microscopic fracture cone dissipates impact energy naturally and effectively. The backing layer absorbs the rest of the energy to ensure penetration is avoided. This impact function provide a ballistic efficiency higher than conventional armor at even thinner plates.
SiC also offers excellent multi-hit capability. Its modular tile design ensures that only the struck area is damaged, while adjacent tiles remain intact. In contrast, steel armor softens and weakens around the impact zone. In addition, silicon carbide is corrosion-resistant, non-magnetic and heat-stable, suitable for extreme environments where steel would fail.
SiC may be brittle and expensive, however, its high strength and energy absorption efficiency make it the material of choice. It achieves higher levels of protection with significantly less weight than steel.
