White Aluminum Oxide Grit
White Aluminum Oxide Grit is a >99% ultra-pure grade of abrasive media. It is increasingly being used in critical, high-performance processes that are sensitive to contamination and cleanliness.
White Aluminum Oxide Grit
White aluminum oxide is the ultra-pure, ultra-tough abrasive for anyone who needs surface perfection. At 99.5% purity, this grade of white aluminum oxide blast media delivers precision and polish in one hard-hitting material. From smoothing skin in a microdermabrasion process to stripping turbine blades for flight, this media doesn’t miss.
What sets it apart? This is grit that is sharp, angular, and tough. White aluminum oxide grains carve through hardened metals and sintered carbide with unmatched ease. Its high recyclability means you can blast again and again in blasting cycles without losing performance or your budget.
Thanks to its consistent grit size, it cuts faster and more evenly than many traditional abrasives. And because white aluminum oxide blast media contains less than 0.2% free silica, it’s a safer, cleaner option than sand. This results in more polish and more refinement.

Frequently Asked Questions (FAQs)
Q1. What is white aluminum oxide blast media?
White aluminum oxide is a high-purity, abrasive blasting media made from fused aluminum oxide crystals. It is extremely hard, reusable, and ideal for precision surface preparation and cleaning without contaminating the substrate.
Q2. What are the key applications of white aluminum oxide blasting media?
- Surface preparation for medical and aerospace components
- Cleaning and micro-etching sensitive materials like glass or titanium
- Surface texturing before coating or plating
- Deburring precision-machined parts
Q3. Is white aluminum oxide safe for use on all materials?
It’s ideal for hard metals, ceramics, glass, and composites. It is not recommended for soft materials like plastic or softwood due to its aggressiveness.
Q4. Can white aluminum oxide be reused?
Yes. It is recyclable for multiple blasting cycles, especially in enclosed systems like blast cabinets. However, it fractures over time, producing finer grit that may affect surface finish.
Q5. Is white aluminum oxide environmentally friendly?
Yes. It is non-toxic, non-reactive, and silica-free, making it a safer alternative to silica sand and compliant with OSHA standards.
