WHITE ALUMINUM OXIDE POWDER, 50 micron (240 grit) 50 lbs(ca1634)
White Aluminum Oxide is the most commonly sold abrasive for sandblasting, surface prep, carving and etching. White Aluminum is friable, as it wears; it slowly shears apart, which has the effect of creating new cutting edges. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower-cutting media blasting grits. Made in the USA.
