  • All our blasting medias are new, not reclaimed.
  • Recommended by OSHA as alternative to silica sand

What Is Friablity?  Short Answer:  How easily/quicky a media shatters on impact and breaks down.  This is different from Hardness Rating.  Sandblasting medias can have the same hardness rating, but completely different Friability Ratings.  Think of Friability as durability.  

  • Brown Fused Aluminum Oxides have a LOW friability, so it will break down slowly, and coarser sizes can be recycled and reclaimed.
  • White Fused Aluminum Oxides have a HIGH friabilty, but the SAME HARDNESS rating (in general) of Brown Fused Aluminum Oxides.  It will thus shatter on impact and break down quickly, without doing as much damage/impact to the substrate.
  • Sinterblast, or Sintered Aluminum Oxide has a MEDIUM friability.  Think of it as the middle ground between Brown Fused and White Fused.  It can be recycled in coarse sizes, but will not have the long life of a Brown Fused AO.  It is often preferred by powdercoating companies due to its lower cost.  If you are just taking off mil scale prior to coating, this is a great media to try out.  THIS IS WHY YOU BLAST AT A 60 PSI WITH THIS MEDIA.  ANYTHING HIGHER AND YOU WILL NOT ACHIEVE GOOD RESULTS.

  • Etching
  • Carving 
  • Grinding
  • Lapping
  • Polishing
  • Surface Preparation

Shipping & Packaging Information:

  • Drum Packaging:  This media is generally sold in 200, 300, or 400 lb fiber drums, depending on the grit size.   (Finer the grit size, the more "fluffy" it is, taking up more space).
  • Discount Pricing:  Please use our Quote Request form to obtain custom pricing on larger quantities, with freight.  Remember to tell us your ship-to address and the total number of lbs or tons you want a bid on. 
  • Loading Dock:  Generally, you need to have a commercial address with loading dock to receive orders over 200lbs.  If you do not, we can ship it to a local terminal and you pick it up yourself from the terminal.  We can also ship to a residential address, but this is very costly and not recommended.
