Aluminum Oxide Abrasive Blasting Media Grit (Standard)
Aluminum Oxide Blasting Media Grit (Standard) is a sharp, long lasting abrasive media that is highly efficient and highly reusable. Harder than most blast media, Aluminum Oxide Blast Media, will clean and etch quickly on all type of surfaces.
Aluminum Oxide Blasting Media Grit (Standard)
When grit matters, aluminum oxide media is the go-to abrasive that never backs down. Angular and to the point in all the right ways, durable aluminum oxide blast media doesn’t just clean a surface; it transforms it. With the power to be recycled many times over, aluminum oxide media is the industry’s most popular abrasive grain for sandblast finishing and surface prep.
Why is it popular? There are several reasons. Aluminum oxide blast media is simple. It’s tough, fast, and it lasts. And it’s affordable. Combine that with a cutting-edge (literally) that works through even hardened metals and sintered carbides effortlessly.
Used extensively in grinding and polishing, aluminum oxide media excels in tumbling operations where time and precision are non-negotiable. From rounding edges quickly to stripping away years of grime, this abrasive performs in a quick, clean, and cost-effective manner.
This blast media is about 50% lighter than metallic alternatives, which means you get twice the particle impact per pound. In other words, you get more hits and less stress on the target, especially on thin or delicate materials. Generally, the larger the grit size, the faster aluminum oxide blast media will cut.
