Boron carbide sand F36, F46 and F54 are premium hard abrasive grains manufactured from high-quality boron carbide raw materials via high-temperature smelting, controlled crushing and strict F-standard particle classification. As one of the hardest artificial abrasives available, boron carbide features outstanding microhardness, exceptional wear resistance and stable chemical inertness against acids, alkalis and high-temperature oxidation. These graded grains maintain sharp angular particle shapes and narrow particle size distribution, delivering consistent cutting performance throughout service cycles.

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.

Boron Carbide F240 F320 F360 For B4C Ceramic
Boron Carbide F240, F320 and F360 graded grits are professional multi-size functional raw materials exclusively developed for high-purity B4C ceramic sintering and advanced ceramic component manufacturing. As one of the hardest man-made ceramic materials, boron carbide features extreme hardness, low density, excellent wear resistance, high temperature stability and outstanding chemical inertness. The combined three mesh specifications cover coarse, medium and fine particle gradation, perfectly solving the structural density and performance uniformity problems of single-size boron carbide ceramics, widely used for producing ballistic ceramic tiles, wear-resistant ceramic parts, high-temperature structural ceramics and industrial corrosion-resistant ceramic components.
