Haixu Abrasives Boron Carbide (B4C) Micro Grit F1000

Haixu Abrasives Boron Carbide (B4C) Micro Grit F1000 is a high-performance ultra-fine abrasive and ceramic functional powder, professionally manufactured for precision finishing, advanced ceramic sintering and high-hardness material processing. Known as “black diamond”, boron carbide ranks among the hardest synthetic materials worldwide, featuring extreme hardness, excellent wear resistance, low density and outstanding chemical inertness, far outperforming conventional alumina and silicon carbide abrasives.

Produced from high-purity boron carbide raw blocks, our F1000 micro grit undergoes precise crushing, superfine grinding and strict FEPA-standard classification. It delivers centralized particle size distribution, zero coarse impurities and good dispersion, avoiding agglomeration and sedimentation during application. With ultra-low iron and impurity content, this premium B4C powder ensures stable chemical performance without scratching or contaminating precision workpieces.

F1000 boron carbide micro grit is tailored for ultra-precision lapping and polishing of hard brittle materials, including hard alloy, ceramic parts, sapphire, glass and precision molds. Its uniform fine particles achieve smooth and flawless surface finishing with consistent material removal efficiency, effectively improving workpiece surface smoothness and dimensional accuracy.

Besides precision polishing, it serves as an ideal sintering additive and filling material for high-density boron carbide ceramics, enhancing ceramic compactness, wear resistance and structural stability. Featured with high temperature resistance, acid and alkali corrosion resistance and long service life, Haixu B4C F1000 micro grit boasts stable batch consistency, making it a reliable raw material for precision manufacturing and advanced ceramic production.
