Copper Slag Sandblasting Abrasive

Our price:

Sharpshot (R) copper slag sandblasting abrasive is available in 3 main grades:

  1. Coarse:  12/30
  2. Medium:  20/50
  3. Fine: 30/60
  4. Very Fine:  40/120 (up to a 1 mil profile, similar to 80 Garnet or 80 grit silica sand.)

Minimum Order:  One pallet in 75lb bags = 3,000 lbs; or One tote bag = 4,000 lbs bulk.  Full van or flatbed loads are usually shipped, but we can ship pallet quantities if necessary (the freight cost per lb dramatically increases if we ship less than a full van or flatbed.)

Packaging:  Bulk (loose), 2 ton supersacks, or smaller 75lb bags/pallet (3,000 lbs/pallet).

Reclaiming and Profile Details:

  • Sharpshot (R) 12/30 grit can be reclaimed up to 5 times, by adding 15% new into the mix.
  • Sharpshot (R) 12/30 will provide a 4.5 to 5.0 mil profile when blasted at 90-100 psi, with a 45 to 90 degree angle, 18-24" distance to Surface.
  • Sharpshot (R) 20/50 grit can be reclaimed twice.(The first blast as a 20/50, and then the second, reclaimed media will be as a 30/60.)
  • Sharpshot (R) 20/50 will provide 2.5-3.0 mil profile when blasted at 90-100 psi, with a 45 to 90 degree angle, 18-24" distance to Surface.  Many users will blast at an 80 psi in order to get more passes out of the material.
  • 30/60 will provide a 2.0 to 2.5 mils profile when blasted at 90-100 psi, with a 45 to 90 degree angle, 18-24" distance to Surface.
  • 30/60 grit cannot be reclaimed, it is just too fine.
  • A 3.0 mils profile is possible with 30/60 but only on new steel without any coating.
  • Media is dense enough to be reclaimed via a Cyclone separator:  115 to 120#'s/cubic foot.
  • Copper slag is a hard, cubical, and aggressive sandblasting media.   Contrary to its name it contains almost no copper.
  • Air cooled, not water quenched.  Angular and Aggressive.
  • Independent studies have shown it to be the fastest cutting slag abrasive.
  • Enviromentally friendly.
  • Approved for recycling in Portland cement.
  • Best abrasive to use when ranked on cutting speed and cost per sq. ft., according to independent NIOSH tests. 
  • Both arsenic and lead testing is done to the material and is therefore on the United States Naval Qualified  Products list. 
  • California Air Resources Board  (CARB) approved for dry outdoor abrasive blasting.
