As a professional waterjet cutting abrasive, green garnet sand shows outstanding cutting performance and stability. Its high specific gravity ensures excellent acceleration in high-pressure water flow, providing strong impact force for cutting stainless steel, carbon steel, aluminum alloy, marble, granite, ceramic and composite materials. It enables smooth cutting edges with no burrs, no cracks and low surface roughness, fully meeting the precision requirements of architectural decoration, mechanical parts and customized material cutting. Meanwhile, its low friability reduces abrasive consumption and improves overall cutting efficiency.
