Garnet Remains the Dominant Abrasive for Waterjet Cutting
Alumina and silicon carbide are optional abrasives for waterjet, but garnet still holds the dominant market share. It delivers the best overall balance of cutting speed, edge finish, nozzle service life, running cost and operational safety.
Harder abrasives like alumina and SiC cut fast yet wear nozzles and focusing tubes heavily. Soft alternatives such as olivine or silica sand are cheap but slow-cutting and unsafe due to free silica. Almandine garnet at 7.5–8 Mohs has sub-angular grains with self-sharpening property. It fractures to form new sharp cutting edges under high pressure, producing straight, clean cuts with minimal taper.
Our refined garnet abrasive is processed by washing, magnetic separation, mica removal and precision grading. It features low impurities, tight particle size distribution and low fines. It feeds steadily with less jamming. Free of free silica, it creates less dust for safer workshop operation.
Standard grades: 80 mesh for general cutting, 120 mesh for fine precision work. It cuts steel, stainless steel, aluminum, titanium, stone, glass and composite materials for shipyards, metal fabrication, new energy and stone workshops. Spent garnet can be cleaned and recycled for reuse to cut costs and reduce waste.
