Aluminum Oxide Powder

Aluminum oxide, synonymously referred to as alumina is a naturally occurring inorganic compound. When processed from its crystalline form that is corundum, a white aluminum oxide powder is given. Aluminum oxide forms on aluminum when it is exposed to atmospheric oxygen. This is something that is explored in anodizing, which is a strengthening process for aluminum.

Aluminum oxide powder receives a variety of industrial applications. One of the reasons why it’s so important is because of its hardness, much like the element itself. It is commonly used as an abrasive in different settings. Because it is strong, hard and cheap to acquire, it is the preferred industrial abrasive when it comes to things such as surface preparation. There are other alternatives in the industry, but their acquisition costs are far too high to be met on a regular basis. An example is industrial diamond, which is one of the hardest substances known. But its production cost is too high to warrant regular usage. As an abrasive substance, the aluminum oxide powder is used in cleaning engines, blades in turbines, as well as surface polishing.

Aluminum oxide powder is used in cutting different surfaces, with the distinguishing characteristics being those that make it suitable for abrasion. It is fine, and the high grain per volume makes it a fast cutter, more so for the surfaces that can be considered as brittle. Its fast cutting action minimizes cut surface stress, and results in smoother, more defined cuts. Other related uses include use in microblasting, metal lapping, and in making of thermal spray coatings. It is also used in chemistry in the catalyzing of reactions, especially in the refineries. It is used to convert hydrogen sulfide to sulfur, in a bid to minimize environmental pollution.

If there are no budget limitations, it is always best to go for originally produced aluminum oxide powder, instead of the reprocessed one. This becomes more important if the powder is to be used for cutting. Original aluminum oxide powder is consistent in the grit size, meaning it is likely to cut faster and more uniformly without leaving rough edges. There are companies that make high temperature aluminum oxide powder so if this is a requirement for you, be sure to mention it to the company as you order. Purities of the powder also vary, with the percentage purity being indicated being referred to as a grade. Ensure you get the grade that is right for you.
