Choose Grit Size:

White fused aluminum oxide is a very high purity oxide, and thus recommended when contamination is an issue to be considered.  It is high on the friability scale, which means it will break down quickly on impact.  It is obtained from the fusion of high purity calcined alumina in electric arc furnaces.  The result is a product with high hardness, high friability, high purity, high melting point, and large crystal size.  The main difference between white and brown fused aluminum oxides is purity and friability.  White is highly pure and highly friable, breaking down quickly.  Brown fused is less pure and has a low friability rating, thus it will not break down nearly as quickly.  However, the hardness rating of the two is about the same.  Note that Friability is not the same as Hardness!

Use this page to order White Fused Aluminum Oxide Sandblasting Abrasives.  Minimum order is 49lbs for coarse grades.   Grades 240 & Finer can be purchased in as small a quantity as 25 lbs.  Repackaging/Processing lead times are 1-3 business days, as we have to repack from drums or supersacks.

SPECIAL NOTE ON 49 LB BOXES!!!  Due to UPS charging huge fees for boxes weighing over 50 lbs, we are forced to short each box a pound or two.  This is why we are now calling our 50lb boxes "49 lb boxes".  This is the best solution we could come up with in order to get you the cheapest shipping rate possible.

LEAD TIME:  Due to ocean freight delays of up to and sometimes longer than 6 months, certain sizes may be out of stock.  So if you can take a nearby corresponding grit size that is close to your ideal size, please let us know in the Comment section of the order page.  

White Fused Aluminum Oxide Specs:

  • Obtained from a reduction fusion of high quality bauxites in electric arc furnaces
  • Electroplating Grade
  • Very Tough: Hardness Rating of 9 on the Mohs scale
  • Can be recycled multiple times
  • High Friability - this means it will shatter on impact and break down quickly, see below.  Good for gunsmithing
  • White in Color
  • Perfect for non slip, anti-skid coatings such as epoxy resin systems
  • Melting Temperature (C) is 2050
  • Alpha macro crystal from trigonal class, hexagonal system.
  • 99.4%+ Aluminum Oxide
  • All our blasting medias are new, not reclaimed.
  • Recommended by OSHA as alternative to silica sand
  • All Aluminum Oxide abrasives unless specifically indicated otherwise, meet the following specifications:
    AA – 59316, Type 1 – Grades A, B, C; GE Aircraft Engine Specifications D5OTF5-S9 Classes A, D and Pratt & Whitney PMC specifications.

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..

Recommended For:

  • Sandblasting
  • Grinding and Cut Off Wheels
  • Coated Abrasives
  • Laminates
  • Paints & Coatings (great for anti slip)
  • Polishing and Lapping
  • Ceramic Shapes and Refractory Applicaions
  • Anti Skid Anti Slip Flooring Grit (Coarse grits like a 24)
  • Surface Preparation
  • Etching, Carving & Gouging:  (Coarse grits like a 36) 
  • Electroplating
  • Wear Resistant Coatings
  • Glass Etching and Glass Carving

Grade Sizing & Mil Profile - These Are Approximations Only!  Approximations are based on using a pressure blaster on hot rolled steel, having tightly adhering mill scale, using a 90-100 psi.  Anchor patterns will vary tremendously based on other variables such as hardness & type of steel, level of corrosion being removed, blast angle, blast distance from the steel, etc.

  • 1 mil profile = 100 grit aluminum oxide
  • 1.5 mil profile = 50 grit aluminum oxide
  • 2 mil profile = 36 grit aluminum oxide
  • 2.5 mil profile = 24 grit aluminum oxide
  • 3 mil profile = 16 grit aluminum oxide
  • 4 mil profile = 12 or 16 grit aluminum oxide
  • Shipping & Packaging Information
  • Pallet Packaging:  This media is generally sold by the metric ton, or per 2,204 lbs.  Also packaged in 50lb bags, 40 bags per pallet.  One net ton per pallet. 
  • Tote Packaging:  We can also package this in 2,200 lb super sacks. (1 metric ton) 
  • 400lb Drum Packaging:  For a couple pennies per lb more, we can package media into 400lb drums for you.  4 drums per pallet or 1,600lbs/pallet.  Please request this when you ask for a quote.  Yes, we can ship a single drum if that is all you need.
  • 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 generally will incur an additional freight charge.
  • Shipping:  Small orders under 200 lbs ship via UPS Ground.  See details below for larger orders.
