Brown fused alumina fine powder 320 mesh 200 mesh

Brown fused alumina fine powder 320 mesh 200 mesh has the advantages of high refractoriness, wear resistance, Impact resistance, erosion resistance, high hardness, high bulk density, and purity. It is mainly used in refractory materials. With the advancement of high-temperature industrial technology and the improvement of process equipment, especially the implementation of new technologies such as blast furnace, converter, ladle, and continuous casting in the metallurgical industry, the adjustment of the variety and structure of refractory materials has been promoted. The proportion of brown fused alumina used in refractory materials has increased. The raw material of brown corundum has played a vital role in adjusting the variety of structures of refractory materials. Brown fused alumina is a refractory raw material in refractory materials. As an essential refractory raw material, it is mainly used in high-temperature industries such as foundry coatings, metallurgy, building materials, and chemicals.

Brown fused alumina fine powder 320 mesh 200 mesh:

Brown fused alumina fine powder 320 mesh 200 mesh is made of high-quality bauxite, anthracite, and iron filings. It is cooled and smelted at a more than 2000 degrees temperature in an electric arc. The available size is 100#-0, 200#-0, 320#-0, and 0-1mm. It is crushed and shaped by a jaw crusher and a ball mill. After magnetic separation, the sieve is divided into various kinds. Its compact texture, high hardness, suitable for the manufacture of ceramics, grinding of high tensile metal and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture advanced refractory materials.

Brown Fused Alumina(FAQ)

How about your delivery time?

Generally, it will take 30 to 60 days after receiving your advance payment. The specific delivery time depends .on the items and the quantity of your order.

What is the shelf life of fused aluminum oxide?

fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely

What is mohs hardness?

Mohs hardness (according to Friedrich Mohs, 1773 – 1839) ascribes a relative hardness value to certain known minerals on a scale ranging from 1 (talc) to 10 (diamond). Accordingly, a mineral is considered harder than another if it can scratch the latter. Please note that these values merely form an

What is grit size?

Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit).  Superfine grits run from 150 and higher.  Grinding wheels usually will be between 24 and 100 grit.  Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher.
