Product Description
Representing the pinnacle of ceramic armor materials, this boron carbide R400 ballistic tile combines extreme hardness with the lightest weight in its class. Our pressureless sintering process for B4C R400 grade achieves near-theoretical density without the prohibitive cost of hot isostatic pressing.
- Industry-Leading Hardness: Vickers hardness exceeding 3000 HV1, surpassed only by diamond and cubic boron nitride, ensures reliable defeat of armor-piercing projectiles
- Ultra-Low Density 2.50 g/cm³: 20% lighter than silicon carbide and 35% lighter than alumina, enabling armor systems under 2.5 kg/ft² for Level IV protection
- R400 Grade Optimization: Controlled carbon-to-boron ratio with sub-micron particle size distribution enhances sinterability while preserving ballistic-grade hardness
- Pressureless Sintering Innovation: Proprietary sintering aid formulation enables full densification at atmospheric pressure, avoiding the high capital cost and size limitations of hot-press tooling

Our B4C R400 tiles are manufactured using advanced pressureless sintering technology that delivers consistent microstructure across the entire batch. Unlike hot-pressed boron carbide which suffers from density gradients near die edges, pressureless sintered tiles exhibit uniform properties throughout, reducing scrap rate and improving ballistic predictability.
This premium tile is the material of choice for special operations forces, law enforcement tactical teams, and helicopter/aircraft armor where every gram counts. The square format enables modular array assembly for compound-curve torso plates via advanced bonding techniques.
