Several factors determine why garnet is the mineral of choice for waterjet cutting. Hardness, density, toughness, and particle size are the main elements that determine cutting speed and nozzle wear.
Garnet has proven itself to have the right balance of these factors to provide the strength and flexibility to cut through tough, thick materials or thin delicate ones. It cuts faster and more efficiently than other abrasives that can be too hard and erode the nozzle too quickly, too soft and break down into dust, or have blunt edges that slow cutting speed. Garnet also has the toughness to be processed into a wide variety of particle sizes, even the smallest, and still maintain its integrity and cutting power. Garnet is also cleaner and generates less dust compared to other abrasives, which helps protect the health of equipment operators.
