Abrasive-stocks is a manufacturer of brown fused aluminum. White fused aluminum oxide is extensively used as a raw material in refractories, ceramic forms, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding, and thousands of other applications. In addition to being offered in the usual mesh, grit, and powder sizes, white fused alumina bubbles, grains, and powders from abrasive-stocks can also be made to order and customized
Brown high purity fused aluminum oxide is available. Because it has fewer impurities than brown or pink fused aluminum oxide, it has a whiter color. It is more friable than brown fused aluminum oxide, in general. A durable, wear-resistant substance with a high ability to survive abrasive chemical attacks (such as acid and alkali) at extremely high temperatures is aluminum oxide, which has a Mohs hardness of 9.
Due to its high degree of refractoriness, remarkable electrical insulating abilities, dielectric properties, and high melting point, brown fused aluminum oxide is a common material choice for a wide range of applications.
To make brown fused alumina powder, high-purity, low-sodium alumina powder is heated to a high melting point, cooled, crystallized, and then crushed. To maintain an even distribution of grain size, tight regulations are applied to the white fused aluminum oxide powder grit.
The grain size distribution of the brown fused alumina powder is closely packed. High purity white corundum powder that has undergone form processing has a full grain, sharp edges, high grinding effectiveness, and high polishing brightness. The grinding effectiveness is significantly higher than that of soft abrasives like silica.
To make white fused alumina powder, high-purity, low-sodium alumina powder is heated to a high melting point, cooled, and then crystallized. The white fused aluminum oxide powder's homogeneity and grain size dispersion are rigorously controlled.
Heating or chemically treating metals or minerals imparts to them the physical properties required to abrade, clean, etch, grind, polish, scour, or otherwise remove material via rubbing action (as in the case of a grinding wheel) or impact (pressure blasting).
Other considerations include cost, availability, thermal stability, and bonding characteristics For any usage, no particular property is required. The polished object has a high finish due to its beautiful appearance frequently utilized in the grinding and polishing of semiconductors, circuit boards, aluminum, steel, and stainless steel. In the glass sector and when grinding and polishing stainless steel, aluminum, copper, and other metal components, it is evidently more effective.
The first choice for sand blasting is brown corundum with uniform particle size and guaranteed quality.
Some of the white aluminium oxide used in industrial production is a fixed model, for example, the ceramic grinding wheel must be grade I brown corundum, grade II can not meet the use standard, and the grinding wheel is cracked and the hardness is not up to the standard.
The first grade brown corundum is suitable for precision casting, wear-resistant materials and other industries with high abrasive requirements.In other words, the final product of fused corundum can only be obtained through coarse crushing, medium crushing, crushing, segmented screening, magnetic separation, fine screening and other links.
At present, as an abrasive, the chemical composition, particle size composition, magnetic content and particle density of fused corundum have national standards.
When selecting, the fused Brown alumina is cooled, divided, crushed, air selected, we should strictly refer to national standards and select high-quality materials.The fixed furnace melting block method and the dump furnace smelting method are generally used in the production of brown corundum at home and abroad.
The two different production methods have their own advantages.
