Garnet sand for shipyard rust blasting is a non-metallic naturally obtainable mineral abrasive belonging to the silicate family. As Almandine garnet, it is the heaviest and hardest of garnets. Due to suitable hardness, physical and chemical properties, it’s used widely for water jet cutting,Sandblasting, water filtration. With its crystalline shape giving a fast cutting action and longer life span, Garnet is a kind of ideal, environment-friendly and efficient natural abrasive.
