Brown Fused Aluminium p40, Abrasive Grain Sizes : p40# for refr

Aluminum Oxide is manufactured in an electric arc furnace that produces an extremely tough, long-lasting grain which is graded to exacting standards. The various macrogrit sizes may be used for all types of bonded abrasive and general industrial applications.
Applications:
It is particularly useful for rough grinding, deburring, snagging and cutting of low-alloy, ferrous materials. Silane coating to improve wet strength in resin wheels is available. Iron Oxide (red coat) is available to increase bonding strength.
