Description

White Fused Alumina
White Fused Alumina(WA),also called White Fused Aluminium Oxide, named by its white color, belongs to the electro fused artificial corundum group and is an important mineral used widely for refractory bricks,refractory castables,pre-cast refractory shapes,other unshaped refractory products,ceramic shapes,metal&ceramic surface preparation,grinding wheels,sandpapers,sanding belts,sandblasting media,lapping and polishing. It’s obtained from reduced fusion of high purity calcined alumina in electric arc furnaces. Calcined alumina is the most important material in aluminium making industry. After the fusion process, the materials become liquid, then cooled down and crushed into different sizes for different applications. Magnetic contents are removed and materials are reshaped by relevant equipments, and then sieved into standard sizes(FEPA,JIS,ANSI) of standard particle distribution. It is characterized by high purity (Al2O3 content≥99%), great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance, which make it to be prefect raw material for all kinds of abrasive tools, including grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives, it also can be used for precision casting and high-refractory materials.
 
White Fused Alumina is a hard, chemically stable and relevantly fragile material with high alumina content, low impurity and stability in high temperatures. It has durable abrasives ability, high fireproof and refractory characters, making it an very important raw material in refractory, bonded abrasives and coated abrasives industries. Similar materials we make are Brown Fused Alumina and Vice White Fused Alumina.
 
White Fused Alumina Characters
1.High Alumina
White Fused Alumina has a Aluminium Oixde(Al2O3) content of more than 99%. The high alumina content is ensured from its raw material which is calcined alumina.The high content of Al2O3 makes it perform well in fireproof and refractory applications.

2.Little Impurities                     
White Fused Alumina has very little impurities, usually less than 0.4% Na2O, less than 0.15 SiO2 and less than 0.15 Fe2O3. It is chemically stable and little impurities make it ideal for refractory uses.

3.High Hardness
The high content of Al2O3 (Aluminum Oxide) makes it to be with very high hardness (Mosh Hardness≥9) and It’s usually utilized for grinding ,cutting, lapping, sandblasting, polishing, surface preparing and also for coated abrasive application, including sandpaper and sand belt.It’s not easy to break and good for abrasives. In abrasives industries, it is used for cutting wheels, grinding wheels etc, also used for coated abrasives applications like sandpapers. It’s white color and little impurities also make it excellent grinding and sandblasting media for preparing and polishing surface of metal, ceramic products etc. WA fines is also an good material for polishing and water jetting in electronics industry.

4.Sharp Edges
White Fused Alumina is a crystal mineral with sharp edges and widely used in sandblasting,cutting and grinding abrasives.
