Low sodium white aluminum oxide is an advanced form of white corudum. White Fused aluminum oxide with Na2O content of less than 0.2% and less than 0.1% is fused from a mixture of low soda alumina powder and special additives. It reduces the smelting process β The content of alumina has increased α Aluminum oxide conversion rate.  β Aluminum oxide is harmful to all aspects of the performance of white alumina without any benefits. It has a negative impact on the microhardness, bending strength, thermodynamic properties, specific gravity, and density of white alumina. The α-phase conversion rate of normal WFA is about 90% with sodium content of 0.3-0.4%. That is not conducive to the better grinding and fire resistance performance of white alumina.

White fused alumina and quartz sand are both white semi-transparent mineral products, and it is difficult to see the difference in appearance with the same particle size and morphology. However, there are significant differences between the two in various aspects, mainly reflected in the following aspects:

White corundum and brown corundum are both fused aluminum oxide raw materials. They are commonly used in industries such as abrasives, refractory, blasting & grinding, and abrasion. However, there are many differences between them.

White aluminum oxide and silicon carbide are commonly raw materials for producing Sharpening stones.  The grinding effect for knives depends on the two raw material characteristics and the production technology of the sharpening stone.

The melting point of fused white fused alumina is 2050-2100 degrees. It has a strong high-temperature stability performance. Used for investment casting shell sand, it has cost and performance advantages. WFA F120 F280 F400 are suitable for precise casting.

Mold steel is usually alloy steel containing multiple elements. It always goes with high-speed steel or carbon steel containing chromium, nickel, manganese, and molybdenum. Users have to choose the proper blasting media for blasting those steels. White aluminum oxide coarse grits such as # 36 mesh # 30 mesh # 24 mesh can efficiently grind and surface treat mold steel.

White aluminum oxide is an extraordinary abrasive powder to produce vibratory buffing media.  The WA powder is a corundum-based abrasive material. It is mostly for grinding steel, iron, non-ferrous alloy, and other metal. Vibratory buffing media made from white aluminum oxide work as buffing and deburring media on most metal-related workpieces.
