Abrasives | FEVI
FEVI sandblasting abrasives include mineral aggregates, aluminum oxide (corundum), glass and ceramic beads, metallic shot and grit, and organic plant-based media for surface cleaning, preparation, and finishing. Select media based on the substrate, coating to be removed, and required finish, verifying grit size and compatibility with your sandblaster. Compare products in our range and request a technical recommendation for your process, from rust removal to satin finishing.

Desired Surface Finish Guides Abrasive Selection
Removing tough coatings, preparing metal for paint adhesion, and creating a uniform satin finish require distinct abrasive actions. Identify base material, contamination type, and target surface profile before choosing. When subsequent coating is required, ensure the surface roughness meets coating specification requirements. A sample test run helps evaluate abrasive performance alongside blast parameters.
Grit Size and Sandblaster Compatibility
Grit size defines grain dimensions and must be matched to nozzle orifice size, metering valves, and working pressure. Coarser media does not automatically yield better results: it must flow properly through equipment while achieving the target finish. Check available mesh sizes and technical ratings on product specification sheets.
Angular Grit vs. Spherical Beads for Different Actions
Angular grains cut, strip, and create surface anchor profiles; spherical beads clean, peen, and satin-finish without cutting the underlying substrate. Hardness, density, and breakdown resistance also dictate performance. For example, glass media is available as angular DUST LUX crushed glass or spherical MICROLUX glass beads. Chemical composition alone does not define blasting action.
Abrasive Recycling and Cost Efficiency
In recycling blast equipment, media reusability depends on particle toughness and air-wash/screening efficiency. Recycled abrasive behaves differently than virgin media. When evaluating media costs, factor in actual consumption rates, processing speed, and surface quality alongside initial bag prices. Reusability rates must be verified under actual production conditions.

| CERABLAST | Ceramic beads | Precision cleaning and satin finishing on aluminum and stainless steel components. |
| STEELBLAST | Steel shot / steel grit | Descaling, heavy deburring, and shot peening in recycling blast rooms/cabinets. |
| BIC BLAST | Sodium bicarbonate (Soda) | Gentle cleaning and degreasing using soft, water-soluble media. |
| PANBLAST | Corn cob grit | Wood restoration, delicate cleaning, and soft metal burnishing. |
| GARBLAST | Almandine garnet | High-performance mineral abrasive for precise surface preparation and stripping. |
| MICROLUX | Glass beads | Cleaning, de-burring, and uniform satin finishing without dimensional change. |
| ECOBLAST | Walnut shell grit | Non-destructive cleaning and deflashing on sensitive substrates. |
| CORIBLAST | Brown fused aluminum oxide (Corundum) | Heavy oxide removal, etching, and anchor pattern creation prior to coating. |
ICE BLAST for Cryogenic Dry Ice Cleaning
ICE BLAST consists of CO₂ dry ice pellets designed for dedicated cryogenic cleaning equipment. Solid CO₂ sublimates upon impact, leaving zero secondary media waste—only the removed contaminants remain for cleanup. Process selection depends on substrate sensitivity and deposit type.

Frequently Asked Questions About Sandblasting Abrasives
What sand should I use in a sandblaster?
The term "sandblasting sand" encompasses various specialized mineral and synthetic media. Always select non-silica abrasives with controlled particle sizing and technical documentation. Matching depends on equipment, substrate, and target finish: olivine, aluminum oxide, glass beads, and organic media serve distinct purposes.
Which abrasive is best for sandblasting wood?
PANBLAST (corn cob) and ECOBLAST (walnut shell) are ideal low-aggression organic media for timber restoration. Choice depends on wood species, condition, and existing finish. Test on a sample area while regulating pressure to avoid raising wood grain.
What is the difference between glass beads and aluminum oxide (corundum)?
MICROLUX glass beads clean and satin-finish surfaces without etching; CORIBLAST brown aluminum oxide cuts, strips, and creates a rough anchor profile. If parts require liquid coating or powder paint, choose the abrasive that delivers the specified anchor profile.
Which abrasive should I use for aluminum and stainless steel?
MICROLUX glass beads and CERABLAST ceramic beads are widely used to clean and satin-finish stainless steel and aluminum without ferrous contamination. Verify media purity and equipment cleanliness to prevent cross-contamination.
Material Technical Documentation and Operating Safety
Consult technical datasheets (TDS) and safety datasheets (SDS) for your selected abrasive. Overall process safety evaluations must account for both the blast media and substrate residues removed during operation. Natural origin, recyclability, and dust generation characteristics should be matched to job-site regulations.
Select Abrasive Media and Grit Size with FEVI
Send FEVI details regarding substrate material, part dimensions, coating to be removed, required finish, and sandblaster model. Including photos or sample parts—and indicating whether your system recycles media—helps our technical team recommend the ideal media and grit size for testing.
