White aluminum oxide sand for refractory material
Product Description
White Aluminium Oxide/White fused alumina is made by Aluminium Oxide powder which is electrically fused at high temperature. It is white. Compared with Brown Aluminium Oxide, its hardness is a little higher, but its toughness is little lower. Our WA has the features of stable quality, well-distributed particle size composition, low magnetic substance content, high bulk density and hardness, good toughness, and high cleanliness, etc. It has been exported to more than 20 countries in Europe, America, Southeast Asia, etc. The abrasive tools made by WA are suitable for grinding high-carbon steel, high-speed steel and chilled steel, etc.
White Fused Alumina belongs to the group of electro-corundum. It is produced by controlled melting of alumina in an electric arc furnace. White fused alumina is iron-free, ultra pure and extremely hard. And it can be applied to so many fields as following:
*White fused alumina for sandblasting
*White fused alumina for precision casting
*White fused alumina for abrasive
*White fused alumina for refractory

White Fused Alumina for sandblasting
White fused alumina for sandblasting abrasive is processed by high quality corundum as raw material and utilized by unique advanced technology. It is characterized by short grinding time, high efficiency, good returns , low price and so on. In particular, its advantages such as high hardness, big specific gravity, good chemical stability and unique self-sharpening , it becomes the first choice for the sandblasting technics, meanwhile, it is also the ideal material for sandblasting and derusting, workpiece cleaning, and polishing.
White Fused Alumina for abrasive
This kind of white fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. It’s the high grade refractory materials.
