Boron Carbide F240 B4C Grit 240 for Armor
Boron Carbide F240 (B4C) grit is a high-performance ceramic raw material specially customized for lightweight ballistic armor manufacturing, widely applied in military body armor plates, tactical helmet liners, vehicle composite armor and aircraft protective components. Known as “black diamond”, boron carbide ranks among the hardest synthetic materials globally, featuring ultra-high hardness, low density and excellent ballistic resistance, making it the core functional material for high-grade lightweight defense armor.

Boron Carbide (B4C) Boron carbide, with the chemical formula B₄C, is an ultra-hard advanced ceramic material widely recognized for its exceptional comprehensive properties. It is manufactured from high-purity boron and carbon raw materials through high-temperature smelting, crushing, purification and precise particle classification. Ranking third in hardness only after diamond and cubic boron nitride, boron carbide features ultra-high hardness, outstanding wear resistance, extreme temperature resistance, excellent chemical inertness and strong neutron absorption capability. It has become an indispensable functional powder for high-temperature sintering, precision abrasives, protective materials, nuclear industry and advanced composite production.
