White Fused Alumina(WFA) is also named as white aluminium oxide,it selects the industrial alumina powder as raw material,
melted in an electrical furnace under high temperature over 2000 degrees,then finally made into different grain size through different process of crushing and reshaping,magnetic separation,screening.It has the characteristics of dense texture,high hardness,high purity,good self-sharpness&grinding ability, small heating power,high efficiency,acid and alkali corrosion resistance, high temperature resistance and good thermal stability.

Why Choose Us?
Now ,the raw material industry has come out vicious competition with price war in China . In order to get more profit , some suppliers think out many strange methods under upon Low price. For example, they add something which very cheap but the appearance is very similar with the goods. No one can find any difference via appearance. The consequence is that clients diffcult to get goods which have surprisingly good effect.I hope that more customers can avoid this kind of loss through my own efforts. Jointly create a good market order
