Copper Slag

Sandblastingabrasives.com SKU: CopperSlagAllGrades

Copper slag is an iron silicate product, containing no actual copper.  It is a by product of copper smelting operations.  As compared to other mineral abrasives, it is 20% more dense, thereby often allowing sandblasters to consume less blast media per blasting job, making it a more cost effective blast media.  If you in a part of the country where you have a choice between copper and coal, give copper a try!

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

  1. Extra Coarse:  12/30  (5/16" Min. nozzle)
  2. Coarse:  20/50  (1/4" Min. Nozzle)
  3. Medium 30/60  (1/8" Min. Nozzle)

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.  Often used by shipyards, oil dericks
  • 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.)  Great for watertower tanks!
  • 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.  Excellent on new steel mil scale, rust grade A and B.
  • A 3.0 mils profile is possible with 30/60 but only on new steel without any coating.
  • 30/60 grit cannot be reclaimed, it is just too fine.
  • For stainless steel or aluminum - 4080 or finer is often used.
  • Copper slag abrasive is dense enough to be reclaimed via a Cyclone separator in coarser sizes only.  It has a  115 to 120#'s/cubic foot.  THIS IS A HIGHER DENSITY THAN COAL SLAG (~20% HIGHER)  AND WILL THUS BLAST FASTER THAN COAL SLAG, AND YOU CAN RECLAIM IT A COUPLE OF TIMES AS WELL.  COAL SLAG HAS A LOWER DENSITY OF AROUND 90 #'s/cubic ft.  Copper will therefore result in less product consumption, less disposal cost, and overall, a more cost-effective media to use when compared with garnet, aluminum oxides, or crushed bottle glass.
  • Specific gravity of ~3.4, just a tad below diamond
  • Low cost; High efficiency; Fast cutting.  Great for many different type of projects.
  • Copper slag is a hard, cubical, and aggressive sandblasting media.   Contrary to its name this media contains no copper!
  • Copper slag is a low dusting media that does not pose the health hazards of silica sand.  
  • Air cooled, not water quenched.  Angular and Aggressive.  **  We do have a slightly less aggressive water cooled copper slag also available.
  • Independent studies have shown it to be the fastest cutting slag abrasive.
  • Always use the finest grit you can, this will provide better coverage, faster speed, less waste and less overall cost.
  • 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.
  • Please email us for a custom freight quotation on this material.   
  • Packaging:  Bulk (loose), 2 ton supersacks, or smaller 75lb bags.
  • Pallet charges will also apply. Shrinkwrapping is available at an additional charge.
  • Priced per net ton, or per 2,000lbs.
  • Email us for custom pricing and multiple truckload prices!
