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.

About us
Yichuan Shengyu Abrasives Co.,Limited is a China producer and supplier of Brown Fused Alumina and White Fused Alumina for refractory, abrasives, blasting and surface preparation industries located in Yichuan County,Luoyang Area,Henan Province.
Our products are with the highest quality for refractory bricks, un-shapped refractory purposes, crucibles, casting and painting, precision cutting,grinding,lapping,polishing,sandblasting,shotblasting,anti-slipping purposes and other applications and industries.
Yichuan County is in central China with highly convenient transportation to all over China by highway, railway and air. It is one of the most important manufacturing bases for Brown Fused Alumina and White Fused Alumina, about 70% of BFA exported out of China is produced here. From mid of 1980s,a few factories of BFA were set up in Yichuan County and supplied to mainly state-owned trading companies of refractory minerals and abrasives grits, as well as manufacturers in refractory and abrasives industries. Shengyu Abrasives was one of these earliest factories, named Weihua at that time.
After that, Yichuan made BFA started to be well known all over China and other countries. The booming of China economy accelerated the development of this industry in Yichuan in 1990s and 2000s, more factories, big or small emerged that that time. From the economic crisis in 2008 to now, this industry has experienced fierce competition and low market and has come to a stable status with hundreds of factories in this area. Shengyu is the one of the earliest and best producer featuring our high standard quality and reasonable prices competing out of so many.
