Zirconia Fused Alumina

Zirconium Fused Alumina is a eutectic structure abrasive of Al2O3 and ZrO2. It is a very durable abrasive material obtained by using high-purity alumina and desiliconized zirconia as the main raw materials. It is melted at high temperature in an electric arc furnace and then rapidly cooled and crystallized. The material has a very fine and uniform microcrystalline structure, which provides high toughness while also ensuring good self-sharpening properties.

GREAT can provide two product series: ZA25 and ZA40, tailored to your unique needs.

25% Zirconia Fused Alumina vs. 40% Zirconia Fused Alumina

Zirconia Alumina is a composite abrasive synthesized from aluminum oxide and zirconium oxide in specific proportions. It harnesses the characteristics of both materials, commonly used in high-performance grinding operations. Here are the main differences between the two:

Item ZA25 ZA40
Zirconium Oxide Content Contains a lower proportion of zirconium oxide (around 25%). Contains a higher proportion of zirconium oxide (around 40%).
Hardness While still hard, it may be slightly softer than ZA40 due to its lower zirconium oxide content. Similar in hardness to ZA25, but the higher zirconium oxide content may provide better wear resistance.
Toughness Good toughness, but not as high as ZA40. The higher content of zirconium oxide offers greater toughness, making it more stable under the pressures of grinding.
Thermal Stability Good thermal stability, but not as high as abrasives with a higher zirconium oxide content. The excellent thermal stability of zirconium oxide makes ZA40 perform better in high-temperature applications.
Application Suitable for general metal grinding, especially when a higher cutting rate is required rather than extreme abrasiveness. Particularly suitable for demanding grinding tasks, such as processing aerospace components, or where extreme wear resistance and thermal stability are required.

The choice between ZA25 and ZA40 largely depends on the specific requirements of the application. If higher wear resistance and thermal stability are needed, ZA40 would be the better choice. 

Conversely, if cost is a factor and the grinding intensity and temperature requirements of the application are not exceedingly high, ZA25 might be more appropriate. The balance between cost and performance should also be considered when making a selection.
