Alluvial garnet is more clean, colour in pink and maintains a sub angular shape that’s ideal abrasive for blasting and waterjet cutting.

A typical abrasive waterjet uses about 0.3-0.8 kg of garnet per minute, or 18-48 kg per hour. But for buyers, the more important figure is garnet cost per meter, because low-quality garnet may cause slower cutting, clogging, rework, and higher total cost. Choosing stable, low-dust waterjet garnet helps reduce interruptions and improve cutting efficiency.
Garnet is the preferred abrasive for stainless steel blasting due to its low free‑iron content, which prevents surface contamination and post‑blast corrosion. Unlike steel grit or aluminum oxide, garnet creates a consistent anchor profile without over‑cutting or warping thin materials. It also generates less respirable dust, improving workplace safety and cost predictability. Typical applications include thin‑gauge tanks, food and pharmaceutical equipment, sanitary piping, and architectural finishes. Always test on scrap material first; 20/40 or 30/60 mesh garnet is generally recommended. SEPPE offers free samples for validation.
Technically yes. Waterjet garnet will remove rust and paint. But whether it’s the right choice depends on what you’re blasting and how you measure productivity.
