Sandblasting and Surface TreatmentGarnet Sand
Natural mineral for blasting and waterjet cutting
Garnet is a naturally occurring, non-toxic, inert abrasive mineral. With its very low free silica content, it is a safer option for blasting than silica sand.
With its high density and hardness, it is used both in open-air blasting and as a cutting abrasive in waterjet machines.
