Why Brown Corundum (Aluminum Oxide) 220 Grit?
220 grit brown corundum is a fine aluminum oxide media that delivers controlled surface finishing without aggressive material removal. It's the standard choice for final surface prep before painting, powder coating, or anodizing. The fine grit creates a smooth, uniform surface profile that promotes excellent coating adhesion.
Ideal Applications
Pre-paint surface preparation, light rust removal on thin-gauge metal, deburring machined parts, cleaning mold surfaces, and restoring stainless steel finishes. Not recommended for heavy rust or thick paint removal — use 80-100 grit aluminum oxide or silicon carbide for aggressive stripping.
Frequently Asked Questions
What's the difference between brown and white aluminum oxide?
Brown corundum (aluminum oxide) is tougher and more economical, ideal for general-purpose blasting. White aluminum oxide is purer, harder, and produces a cleaner surface finish — preferred for precision work and non-ferrous metals. Brown is the better value for most shop applications.
How many times can this media be reused?
Brown corundum can typically be reused 5-8 times depending on the application and surface hardness. It breaks down more slowly than glass bead, making it one of the most cost-effective reusable media options.

Frequently Asked Questions
What is brown corundum?
Brown corundum is aluminum oxide (Al₂O₃), a widely used industrial abrasive. At 220 grit, it provides fine surface finishing suitable for paint preparation, precision etching, and smooth finishing work.
Can I reuse this media?
Brown corundum can be reused 2-3 times depending on the application and material being blasted. It breaks down gradually with each use, producing a finer finish over time.
What is the difference between 220 grit and coarser media?
220 grit creates a very fine surface profile — ideal for preparing surfaces for paint, coating, or bonding where a smooth anchor pattern is needed. Use 60-80 grit for aggressive rust removal, 100-120 for general prep, and 220 for final profiling and light etching.
How much media do I need for a typical job?
A small rust spot (1-2 sq ft) uses about 1-2 lbs of media. A full car panel takes 5-10 lbs depending on coating thickness. Since aluminum oxide is reusable 4-5 times, your effective cost per job is significantly less than the initial purchase. For large jobs, buy in bulk.
Quick Setup Guide
Pour media into your sandblaster's gravity hopper or siphon container. 220 grit is a fine abrasive — set your blaster to 60-80 PSI for light cleaning and surface profiling, or 90-120 PSI for more aggressive material removal. Maintain a 6-8 inch standoff distance for even coverage. This media can be recycled 3-5 times before particles break down too small to be effective. Sieve recovered media through a mesh screen to remove debris before reloading. Store in a dry container — moisture causes clumping and inconsistent flow.
