Aluminum oxide and silicon carbide

Aluminum oxide is excellent for cutting and heavy cleaning and for pre-finish surface preparation. Available in grit sizes 16 - 240. Fine powders - sizes 280 to 1200 - also available. Ample quantities of all common sizes are stocked at our warehouse.

ANSI is the American National Standards Institute. ANSI standard B74.12~2001 gives two separate specifications, one for abrasives to be used for grinding wheel and general industrial applications (table 2), one for abrasives to be used for blasting (table 3). Table 3 applies to  aluminum oxide and is shown below:
