ALC 40097 150 Grit Aluminum Oxide - 25 lbs.

25lbs of 150 grit aluminum oxide for a finer finish. 0.0035" in size and 9.0 mohs on the hardness scale, it cuts quickly and effectively. Best used in blast cabinets or where the abrasive is recycled, it stays sharp and its life cycle is longer than others. Ideal for penetrating deep into hard surfaces and delivering a semi-coarse finish. Can also be used to etch glass. Note: the size of the blaster nozzle should be three to four times the size of the abrasive's grit for maximum efficiency, the larger the nozzle, the more CFM of air is needed.
