Mulgrit™ Brown Fused Aluminum Oxide – Blasting Grain

Download: Technical Data Sheet | Safety Data Sheet (SDS)

Description:

Aluminum Oxide is manufactured in an electric arc furnace that produces an extremely tough, long-lasting grain which is graded to macrogrit exacting standards. It may be repeatedly recirculated and is chemically stable and not affected by alkalis, acids or harmful atmospheres.

Applications:

Mulgrit™ is suitable for wet or dry surface preparation, cleaning, deburring and cutting of various metals, ceramics, glass, wood, rubber, plastic, stone and composite materials.
