Why use Aluminum Oxide to do sandblasting?
Aluminum oxide, also known as alumina, is a commonly used abrasive material in sandblasting due to its various beneficial properties. Here are some reasons why aluminum oxide is commonly used for sandblasting:
Hardness: Aluminum oxide is a hard abrasive material with a Mohs hardness of 9, which is just below the hardness of diamond. This makes it highly effective at removing tough coatings, corrosion, rust, and other contaminants from surfaces. Its hardness also allows for multiple reuse before it breaks down, making it cost-effective.
Abrasive properties: Aluminum oxide has sharp edges and angular shapes, which allow it to effectively abrade and remove material from the surface being blasted. It is a versatile abrasive that can be used on a wide range of surfaces, including metal, wood, concrete, glass, and ceramics.
Abrasive consistency: Aluminum oxide abrasives are available in a variety of grit sizes, ranging from very fine to very coarse, allowing for different levels of surface roughness and finish. This allows for precise control over the blasting process, making it suitable for a wide range of applications.
Chemical inertness: Aluminum oxide is chemically inert, which means it does not react with most materials. This makes it suitable for use on sensitive materials and surfaces, such as those that may be prone to chemical reactions or discoloration.
Availability and cost-effectiveness: Aluminum oxide is widely available and relatively inexpensive compared to some other abrasive materials, making it a cost-effective choice for sandblasting operations.
Environmental friendliness: Aluminum oxide is an environmentally friendly abrasive material as it is not toxic, and it does not contain any hazardous materials. It is also recyclable and can be used multiple times before disposal, reducing waste and environmental impact.
Versatility: Aluminum oxide can be used for various sandblasting applications, including surface preparation, paint and coating removal, rust and corrosion removal, deburring, and etching. Its versatility makes it a preferred choice for many sandblasting operations.
