Frequently Asked Questions
How many times can this media be recycled?
Typical recycle count 4–7 times depending on use, nozzle and system setup.
Is there crystalline silica?
Testing indicates no detectable crystalline silica — always consult SDS for current data.
Usage & Typical Applications
Aluminum Oxide is commonly used where aggressive cleaning and profile are required — suitable for new steel, weld cleaning, and certain coating prep jobs. Adjust pressure and nozzle choice to balance consumption and production rate.
How to choose grit size
Select the particle size based on desired profile and surface condition — finer grits for delicate surfaces, coarser grits for heavy rust/scale removal.
