Sintered aluminum oxide is excellent abrasive choice for powdercoating and anti-skid flooring applications. This product is a hard and unyielding abrasive, semi-friable, with a price point lower than fused aluminum oxides. Exceptionally well-suited for use with air-compressed jet-blasting equipment, both pressure and suction. Use this page to order a 50lb box of Sinterblast, grit sizes 16 through 150. Standard packaging is 40, 50 lb bags/pallet. Repackaging/Processing lead times are 1-3 business days.
What Is Sinterblast?
Sinterblast is a new sandblasting abrasive made from the same raw feed stock as fused aluminum oxides (Bauxite). Sinterblast is created via a sintering process, not the normal fusing process. This sintering process uses less electricity than fusing does, allowing this media to be priced significantly lower than brown fused aluminum oxides.
Sinterblast is a high temperature calcined bauxite abrasive grain; 78 pecent aluminum oxide, 13 percent iron oxide. It is often used as to replace brown fused aluminum oxide due to its lower cost. Sinterblast is a very hard, tough abrasive, allowing it to be recycled many times, just like regular brown fused aluminum oxides.
Sinterblast is just as hard as fused aluminum oxide, but it has a lower bulk density and is more friable. The big difference is its medium friability. Consider it in the middle between brown fused (low friability) aluminum oxide and white fused (highly friable) aluminum oxides.
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.
PSI Information:
Sinterblast should be blasted at a 60 psi in general, due to its medium Friability. This is a much lower psi than regular brown fused aluminum oxides (80-90), so please make a note of this. You will not obtain ideal results if you do not start with a lower psi. Sinterblast is slightly more friable than brown fused media, and this is why you need to use a lower psi. Since you can reclaim this media multiple times, the cost savings of switching to Sinterblast can be impressive. Some of our clients have switched 100% to Sinterblast (from brown fused aluminum oxide).
What Is Friability? Short Answer: How easily/quickly 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.
Sizing - 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.
