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

  • Coarse:  12/30
  • Medium:  20/50
  • Fine: 30/60
  • Very Fine:  40/80 (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).

Typical Applications for Iron Silicate Copper Slag:

  • Sandblasting, Surface Prep
  • Grinding Wheels (20/50 Medium)
  • Corrosion Cleaning
  • Cement Additive
  • Garment & Textile Blasting
  • Jean & Clothing Sandblasting
  • Offshore oil pipeline blasting
  • Waterjet Cutting Deepsea Structures
  • Roofing Granules - 12/30 for tab shingles, 40/120 for felt and polyester roll roofing 
  • Pipeline Blasting
  • Golf Course Filler - ballast for artificial turf (30/60)
  • Additive to make high density concrete for nuclear shielding (40/120)
  • Paints and Coatings
  • Blast Cleaning
  • Asphault anti-skid additive (30/60)
  • Slag Wool Insulation

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.  
  • 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.
  • 40/80:  This is an extra fine grade abrasive for use on carpet, plastic and wood. This product  is often used for antique restoration and cars. This fine sizing typically - with properly working equipment - produces a profile of less than 1.5 mil.  Some people like it more than 3060 because it blasts faster, due to the smaller particle size, and more particles hitting the surface simultaneously.  You can get a 1.0 - 1.5 mil profile out of this grade, if you manipulate angle, distance, pressure, etc.  As long as all you are doing is removing mil scale, this might be perfect.  But if you are needing to really achieve a particular mil profile over 1.5, you may want to consider 3060.
  • 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 AND WILL THUS BLAST FASTER THAN COAL SLAG, AND YOU CAN RECLAIM IT A COUPLE OF TIMES AS WELL.  THIS IS NOT THE CASE WITH COAL SLAG, WHICH HAS A LOWER DENSITY OF AROUND 90 #'s/cubic ft.
  • 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.  **  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.
  • 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.
