Garnet abrasive
Reliable Abrasive for Waterjet Cutting & Surface Blasting
- High hardness (7.5-8 Mohs) for aggressive yet controlled abrasion.
- Low dust and non-toxic composition for safer work environments.
- Recyclable up to 5-6 times, lowering overall costs by 30-50%.
- Versatile mesh sizes for precision in blasting and cutting.
- Environmentally sustainable with minimal free silica (<1%).
- Efficiency and Speed: Cuts blasting time by 30-50% with high specific gravity and sharp grains, reducing labor and media consumption (e.g., 10-20% lower than slag).
- Safety and Health: Low dust minimizes inhalation risks; silica-free (<1%) prevents silicosis; non-toxic and inert for marine/offshore use.
- Cost-Effectiveness: Recyclable 3-6 times; lower disposal costs due to non-hazardous waste classification.
- Environmental Compliance: Eco-friendly with no heavy metals; aligns with REACH/RoHS; sustainable mining practices.
- Performance Reliability: Consistent profiles (2.5-4.5 mils) for better coating adhesion; minimal embedment (<1%) ensures clean surfaces.
- Versatility: Effective in wet/dry blasting; durable under high pressure without fracturing excessively.
