Pumice Grit 46 mesh

About Pumice Grit 46 Mesh

Pumice is a naturally occurring volcanic mineral characterized by its frothy, vesicular structure. When crushed and graded to 46 mesh, it produces an angular, lightweight grit with moderate hardness. This abrasive is particularly valued in operations where ferrous contamination must be avoided and where a softer touch is required compared to aluminum oxide or garnet.

The 46 mesh designation indicates a controlled particle size distribution that passes through a sieve with openings of approximately 354 microns. This medium-fine grade delivers consistent cleaning action across the blast pattern, making it suitable for both suction-fed and pressure-fed blasting systems. Operators can expect effective removal of light rust, mill scale, carbon deposits, and weathered coatings while preserving dimensional tolerances on sensitive substrates.

Key Characteristics

• Lightweight mineral composition: Reduces operator fatigue and allows blasting at lower pressures.
• Angular particle shape: Provides mechanical cleaning action without aggressive cutting.
• Low free silica content: Supports safer working conditions when used with proper dust controls.
• Non-ferrous: Eliminates risk of post-blast rust bloom on stainless steel and non-ferrous alloys.
• Recyclable: Can be reused multiple times in enclosed blasting cabinets depending on impact velocity and substrate hardness.

Typical Applications

Pumice Grit 46 mesh is specified across a range of industrial surface preparation and cleaning tasks:

• Precision parts cleaning: Removes carbon, varnish, and light oxidation from engine components, molds, and tooling without dimensional change.
• Architectural restoration: Cleans stone, brick, and concrete surfaces while preserving original surface texture and patina.
• Electronics and electrical cleaning: Non-conductive and non-ferrous properties make it suitable for cleaning insulators, contacts, and sensitive assemblies.
• Aerospace and defense: Used for light deburring and surface preparation on aluminum and magnesium components where ferrous contamination is prohibited.
• Glass etching and finishing: Produces a uniform matte finish on glass and ceramic surfaces.
