White Aluminum Oxide Blast Media is a 99.5% ultra-pure grade blasting media. White aluminum oxide blast media has a wide variety of applications, including cleaning engine heads, valves, pistons, and turbine blades in the aircraft and automotive industries. White aluminum oxide is also an excellent choice for preparing a hard surface for painting. White aluminum oxide blast media contains less than 0.2% free silica and is safer to use than sand. The grit size is consistent and cuts much faster than other sandblasting media, leaving a smoother surface.
