Zirconia Fused Alumina Introduction


Zirconia fused aluminum oxide is formed after its main zircon sand is smelted at high temperature in electric arc furnace.It features good tenacity,compact structure,high strength and fine thernak shock resistance.

It is a kind of high quality abrasive material, with the characteristic of high intensity, high toughness and high temperature resisting, this type of grains can be used to produce high quality overload grinding wheel. And also it can be used to grind steel, cast, titanium alloy and nickel alloy ect. Also it can be used in producing refractory products.


Zirconia Fused Alumina Characteristics



Zirconia Fused Alumina contains Zirconium Oxide(ZrO2) and Aluminium Oxide(Al2O3) which are important chemical contents for refractory performance. Ideal material for refractory bricks.

High Strength

Zirconia Fused Alumina has high hardness and strength(about 400N). It’s one of the most hard and strong artificial corundum.

Sharp Grain

Like other corundum, grains of ZA is sharp edged material ideal for cutting, lapping, polishing etc of metal surface.

High Density

Zirconia Fused Alumina has true gravity of about 4.3g/cm3, compared to about 3.9g/cm3 of Brown Fused Alumina and 3.6g/cm3 of White Fused Alumina. And bulk density about 2.2g/cm3 which is also much higher than other corundum. It’s used for heavy duty bonded abrasive products.

There’re two grades of Zirconia Fused Alumina by its content of Zirconium Oxide(ZrO2): ZA25 and ZA40 named by their content.

Available Sizes: 0-1mm,1-3mm,3-5mm, F8-F220 for abrasive use.
