Sharpshot Copper Slag (Iron Silicate) Data Page

  • 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.
  • Copper slag is a hard, cubical, and aggressive sandblasting media.   Contrary to its name it contains almost no copper!


Packaging and Freight Info:

  • Packaging:  Bulk (loose), supersacks, or bags.

Reclaiming Copper Slag Tips: 

  • To increase the number of uses, turn down the psi until you cannot see the material come out of the nozzle. If you can see it, it will not cut well, as you have too much in your air stream.  Start with a psi of 80 and adjust it upwards from there. A higher psi will not equal a faster or better cutting rate.
  • Try adding 15% new media back into the mix as you blast reclaimed material.
  • Can also be mixed in with steel shot and grit.
  • Dense enough to be used in a Cyclone blasting machine.
  • When blasting pipelines, try blasting new media on the inside first, then the reclaimed material on the exterior second.  In this manner your first pass will be as a 1230, and the second as a 2050. 
  • To get at least three passes:  Start with a 1230, turn down the psi, and consider adding 15% new into your mix.  You can often obtain 5 passes if you do this.
  • 32% iron:  It will be attracted to a magnet and is dense enough to be reclaimed.
  • Blastox is available - please specify percentage required when requesting a quote (15% or 20%).
