emery abrasives

emery  is an extremely sharp, long lasting, blasting abrasive that can be recycled many times. It is the most widely used abrasive in blast finishing and surface preparation because of its cost, longevity and hardness. Harder than other commonly used blasting materials, aluminum oxide grains penetrate and cut even the hardest metals and sintered carbide.
