Aluminum Oxide

Detailed information is given about aluminum oxide grit used in the sandblasting process at this web page. Our company sells aluminum oxide grit at different sizes. Aluminum oxide mineral is rated according to its purity: white, pink and brown colors available. It is commonly called aluminum oxide, alumina, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. It is the most widely used abrasive in blast finishing and surface preparation because of its longevity and hardness. Aluminum oxide used as a grinding and polishing media is a cost effective and efficient media for tumbling operations that require quick edge rounding, surfacing finishing or cleaning. Approximately 50% lighter than metallic media, aluminum oxide abrasive grain has twice as many particles per pound. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower cutting media. Aluminum oxide grit has a wide variety of applications, from cleaning engine heads, valves, pistons and turbine blades in the aircraft industry to lettering in monument and marker inscriptions. It is also commonly used for matte finishing, as well as cleaning and preparing parts for metalizing, plating and welding. Aluminum oxide abrasive grain is the best choice for an abrasive sand blasting and polishing grain as well as for preparing a surface for painting. White aluminum oxide mineral should be preferred especially while blasting stainless materials because of its high purity level. Sandblasting of stainless steels, titanium and aluminum alloys, copper and brass alloys and also porcelain-based materials with white aluminum oxide abrasive is preferred. It produces much less dust than brown aluminum oxide also and provides much more clean surface finish. Brown aluminum oxide mineral, because it contains free state iron damages the property of the surface rustproofing. Intensive use can also cause discoloration on the surface. Aluminium oxide abrasive is moisture sensitive material and should definitely not be exposed to humidity during storage.
