For industrial applications, certified crude bauxite must be crushed and graded to create the white or brown virgin fused abrasive known as aluminum oxide. Aluminum oxide grit price is a durable and long-lasting abrasive blasting media that can be recycled multiple times and is known to be economical in the blasting process because of its recyclability, which gives us the advantage of not having to buy additional blasting media. It can provide a deep anchor pattern or etch in applications where surface preparation is important or challenging, like surface profiling for subsequent protective coatings, because of its chemical properties and characteristics. It is a versatile type of blasting media because of its high density and angular sharpness; used in both wet and dry blasting processes.
Types of Aluminum Oxide
There are mainly three categories of aluminum oxide grit available on the basis of their colors:
- White Aluminum Oxide Grit
- Brown Aluminum Oxide Grit
- Black Aluminum Oxide Grit
White Aluminum Oxide Grit
White aluminum oxide grit will produce less dust because it is friable, which refers to how quickly and easily an abrasive material breaks down and smashes on impact. Hardness Rating is different from this. The hardness rating of sand blasting media can be the same, yet the friability ratings can be radically different. Friability and durability are related terms, and medium-density abrasives are accessible in a variety of grains, including coarse, medium, fine, and powder. When high purity and high friability abrasives are required, white aluminum oxide grit is used.
Features of White Aluminum Oxide Grit
- Manufacturer of aluminum oxide grit of the highest caliber.
- The grit's purity in aluminum oxide.
- Grit made of aluminum oxide: properties and chemical stability.
Applications of White Aluminum Oxide Grit
- Prior to painting
- Aluminum oxide grit is used to clean the surface being blasted of debris, rust, corrosion, etc., such as in the case of an automobile.
Brown Aluminum Oxide Grit
High-grade aluminum and cutting-edge methods are used in the manufacturing of brown aluminum oxide. It is examined on a number of criteria by our vendors to guarantee its quality. Brown fused aluminum oxide is advised for use in bonded abrasives such as grinding wheels and cutoff wheels, coated abrasives (paper & cloth), sand blasting abrasive media, as well as refractory applications due to their high toughness.
Applications of Brown Aluminum Oxide Grit
- Sand blasting is the best method for cleaning and smoothing metal surfaces.
- Flooring with anti-skid.
- When using colored epoxy, white is also an option if pigmentation is a problem.
- When there are loose particles on a surface, prepare it.
Black Aluminum Oxide Grit
One of the hardest minerals readily available is the black aluminum oxide grit. By electrifying bauxite, iron oxide, and small components in a moving circular segment heater, black aluminum oxide is formed.
Applications of Black Aluminum Oxide Grit
- Water jet cutting.
- Sand blasting/blast cleaning.
- Denim blasting.
- Grinding and polishing of stainless steel.
- Optical glass, bamboo, or other materials.
Aluminum Oxide Grit Size
- 1 mil profile = 100 grit Al2O3
- 1.5 mil profile = 50 grit Al2O3
- 2 mil profile = 36 grit Al2O3
- 2.5 mil profile = 24 grit Al2O3
- 3 mil profile = 16 grit Al2O3
- 4 mil profile = 12 - 16 grit Al2O3
Grit Sizes: A very simple and non-technical way of understanding coarse grit sizes is to use a 1/2" (a half-inch) mesh square as an eg. A 50 grit will have 50 tiny holes in that 1/2" square and thus particles are 1/50th of a half-inch or finer than that. A 10 grit will have particles of 1/10th inch, and so on.
