Coated abrasives abrasive P special corundum sand　　Brown had high hardness, toughness, sharp grinding strength, good chemical stability. Is an important raw material of abrasive, abrasive, sandpaper, waterproof sandpaper, sand disk, soft belt, hand pull sandpaper, flap wheel, one hundred sheets, eme

Brown fused alumina is a kind of artificial corundum produced by high temperature smelting of natural bauxite. Although the main component is Aluminium Oxide, it still contains a lot of other chemical components such as silica, iron oxide, titanium oxide, etc.

We loading Brown Fused Alumina 22# 24# 46# 54# yesterday, and they will be shipping to to France soon.

Brown fused alumina shows blue after calcination at 1350℃ temperature. The impurities existed in the grains will be separated out & vaporized . The surface of each particle changes coarser, improves the hydrophilicity greatly. After 1350℃ calcinations ,cracks from crushing and crystal cooling proces

High resistance to polishing, abrasion and weathering*Chemical stability under acid/alkali agents and intense heat applications

Low Heat-treated:Low temperature treatment enhances the toughness of abrasive grain, also improves cleanliness.Heat-treated abrasive materials can be used for the fabrication of grinding wheels and coated abrasives.

A Refractory is a material which can withstand high temperature and at the same time retains its structure and are physically & chemically stable.
