Product Description
This multi-curve boron carbide R400 ballistic plate sets the benchmark for lightweight Level IV body armor. The anatomically contoured multi-curve geometry combined with ultra-light B4C R400 achieves standalone Level IV protection at under 2.5 kg per plate - the lightest in its class.
- Dual-Radius Contour: Cylindrical curve (R450mm) for vertical torso wrap combined with spherical curve (R350mm) for horizontal thoracic conformity, providing the closest anatomical fit among rigid plate designs
- Reduced Standoff Gap: Multi-curve geometry minimizes the air gap between plate and body, improving both ballistic performance (reduced back-face signature) and wearer mobility
- Pressureless Sintering Precision: Our unique sag-control sintering process for curved B4C maintains the dual-radius contour within ±3mm tolerance without the distortion common in hot-pressed curved plates
- Weight Under 2.5 kg: The combination of 2.50 g/cm3 B4C R400 and optimized thickness profiling achieves standalone plate weight below 2.5 kg in SAPI Medium, a 25% reduction versus equivalent SiC plates
| Threat | Projectile | Plate Weight (M) | Result |
|---|---|---|---|
| NIJ Level IV | 30-06 M2 AP | < 2.5 kg | ✓ Standalone |
| NIJ Level III | 7.62x51mm M80 Ball | < 2.5 kg | ✓ 6-shot Multi-Hit |
Engineered for special operations forces, close protection details, and tactical law enforcement units where every gram matters. The multi-curve fit enables extended wear during 12+ hour missions without the fatigue associated with flat or single-curve plates. Compatible with low-visibility plate carriers for covert protection operations.
Elite Protection Standard: This plate is manufactured to the highest quality standards with 100% ultrasonic inspection and individual ballistic witness testing available upon request. Lead time for custom multi-curve profiles: 20-30 business days.
