White fused alumina fine powder 200-0 is made of high-quality industrial alumina powder cooled and smelted at a more than 2000 degrees temperature in an electric arc. White fused alumina is crushed and shaped by a jaw crusher and a ball mill; The fine powder is the product passing through the 200 mesh screen in the refractory sand production line. Its compact texture, high hardness, suitable for the manufacture of ceramics, grinding of high tensile metal and grinding, polishing, sandblasting, precision casting, etc. It can be used as a high-quality powder for shaped refractory and amorphous refractory.
Introduce white fused alumina fine powder 200-0:
White fused alumina Using high-quality alumina powder as raw material by refining and crystallizing in an electric arc furnace at high temperature. It has white colour, is slightly harder and has lower toughness compared with brown fused alumina. Its microhardness is 2200-2300kg/mm² with high purity, good acid and caustic corrosion resistance, high-temperature resistance and good thermal stability.

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.
Corundum is the most frequently used abrasive. The purer the corundum, the harder it also is, which can be determined from the colour. The toughness can be increased by adding various metal oxides and by shortening the cooling process in production. The following distinctions are made: Brown fused alumina with
This decision is made by the type of abrasive you have selected or the type of process you will be performing. Glue – A straight animal hide glue that is used to adhere the abrasive particles to the backing. Referred to as “Glue Bond”. Resin – A synthetic resin that
Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications. Its applications include aluminum, ferrous metals (including alloy steel), hardwood, and leather. Crocus – Crocus
Yes, No problem, but Customer resposiable for the charge.
Silicon carbide is a chemical compound of silicon and carbon and belongs to the group of carbides. The chemical formula is SiC.Silicon carbide is at the same time the hardest and lightest ceramic material and is also highly resistant against acids and alkaline solutions.
