Abrasive Garnet Garnet is a mineral abrasive produced from naturally occurring almandite garnet. It is produced by processingbeach sand and grading to exact specifications. Due to its low free silica, Garnet abrasive is widely used insand/grit blasting and now widely popular for waterjet cutting. Garnet is cost effective, environmentally andoperator friendly, alternative to silica sands and minerals slags and will provide a class Sa3 White Metalfinish. Garnet particles are dense, hard and sharp and free of heavy metals or toxic components. The lowfriability of garnet permits recycling up to 5-8 times and the relatively high density ensures fast blasting speeds.
